Hi, @Manouchehri. I wonder if there is any document discribing diffrences between each suffix of https://rfc3161.ai.moda/[*]?

Hello users of Trusted Timestamps. I would like to add my own site to the list: https://timestampit.com/. TimeStampIt! is a TSA and it is only a TSA. We do not however offer RFC3161 timestamps, but a new design based on plain text encoded trusted timestamps. I built it because a) RFC3161 timestamps are not easy to work with, and b) there really was not a good dedicated TSA that felt like I could build a commercial application on top of.

It is brand new and experimental. I would love any feedback you might have on it! info at timestampit dot com 💚. If there is enough demand I could even add support for RFC3161 timestamps. But honestly I would rather keep innovating in other directions.

@rschultheis RFC3161 is super easy to work with, lots of programs support it out of the box. I've been using it for years on all of my important PDFs, even those non-technical can see the timestamps easily.

timestampit without RFC 3161 and RFC 5816 support doesn't make a lot of sense here in these topic.
In fact I would argue that since RFC 3161 and RFC 5816 are the standards and are supported by so many programs that is still relevant, the magic part should be the part to be able to verify in the future that the file was really timestamped 23 years ago... I've been testing TSA's for a long time and basically is almost impossible once the TSA expires to proof anything since it will start to give errors... since CRL and or OCSP usually stop working and stops being possible to verify anything.

timestampit could have say a different key for every year using RSA 8192 bit SHA512 key to timestamp using RFC 3161 and RFC 5816, and say 150 years of year key lifetime, the main Root with say 500 years lifetime, RSA 16384 bit SHA512. and every year a new key with 150 years of key lifetime.

TimeStampit Root Key (RSA 16384 bit SHA512) [From: 2024-08-12 - Until: 2524-08-12]

TimeStampit 2024 Key (RSA 8192 bit SHA512) [From: 2024-08-13 -> Until: 2174-12-31] [signs between 2024-08-13 00:00:00 until 2024-12-31 23:59:59]
TimeStampit 2025 Key (RSA 8192 bit SHA512) [From: 2025-01-01 -> Until: 2175-12-31] [signs between 2025-01-01 00:00:00 until 2025-12-31 23:59:59]
TimeStampit 2026 Key (RSA 8192 bit SHA512) [From: 2026-01-01 -> Until: 2176-12-31] [signs between 2026-01-01 00:00:00 until 2026-12-31 23:59:59]
TimeStampit 2026 Key (RSA 8192 bit SHA512) [From: 2026-01-01 -> Until: 2176-12-31] [signs between 2026-01-01 00:00:00 until 2026-12-31 23:59:59]

If the CRL('s) can be included within the signature (still doesn't happen in most programs) then theoretically the timestamp could be believed until its expiration date... as long the company itself doesn't have any troubles coming up like the private key being stolen or cracked.

RSA 16834 bit key with SHA512 should be fine for the Root, but usually can't be used for the final signing key because it will give too many errors at least in my tests it would fail on most signing programs because would take too many memory/ space reserved for the signature.

NIST P-521 could theoretically be used but the problem is that in reality the security level of it should be lower than even RSA 3072 bit key at least if quantum computing is used to try to find the private key.

Ok... but what if TimeStampit doesn't want to support RFC 3161 and RFC 5816?
In what it would be different from other services online like: https://truetimestamp.org , https://opentimestamps.org , https://tzstamp.io , https://timestamp.decred.org and https://notbot.me ? What happens if TimeStampit closes in 6 years time, how would people be able to prove to others that timestamp is real? Some of the services above include some sort of bitcoin or other coin integration to make it more easy to proof in the future (as long those continue to exist)... in some cases judges may not accept them since it wouldn't be easy to verify by themselves and they may or may not believe experts, if it seems magic mumbojumbo... and to my knowledge there is no standard log database for timestamp similar to Certificate Transparency (where people can search for the certificate from multiple sources using for example: https://crt.sh ) where I think the certificate companies need to publish to more than one log database (at least one being from others not related to that company) in order for others to trust it and be able to verify things after the fact.

Hi @JohnPlanetary , thank you for this feedback.

I don't want to take over this excellent gist about RFC3161 TSAs (thank you @Manouchehri ) with a discussion of TimestampIt!, therefore I've started a new gist to respond: https://gist.github.com/rschultheis/ea3b17017f520b4b3dcca270fc8dd1b6.

I'd love to keep the discussion going over there, but to quickly respond to one point:

What happens if TimeStampit closes in 6 years time, how would people be able to prove to others that timestamp is real?

This is what the TimestampIt! verification key replica repos are for: https://github.com/timestampit/keychain/. More info in my new gist 💚

Hi, @Manouchehri. I wonder if there is any document discribing diffrences between each suffix of https://rfc3161.ai.moda/[*]?

That would be really great as I am wondering what are the differences too!

The https://rfc3161.ai.moda/[*] load balancer sounds really great. Unfortunately we are not able to use it as our custom (time)stamping service needs to have list of all used TSA CAs root certificates to consider them trusted.

Would it be possible to have a list with links to root certificates of all active CAs used for https://rfc3161.ai.moda/[*] so we could download them?

maybe it will be useful to someone:

If you choose one between the Adobe: European Union Trusted Lists, and Adobe Approved Trust List, which is more widely accepted? I'm assuming the EU has a higher level of trust and works everywhere?

Symantec's timestamp server appears to be defunct. See this.

We switched to the Azure Code Signing timestamp server: http://timestamp.acs.microsoft.com

Would it be possible to have a list with links to root certificates of all active CAs used for https://rfc3161.ai.moda/[*] so we could download them?

I've exposed https://rfc3161.ai.moda/servers.json for now, does that work or still not quite?

Thanks, I've added that one for Windows signing on https://rfc3161.ai.moda!

I've exposed https://rfc3161.ai.moda/servers.json for now, does that work or still not quite?

I mean list of URLs to all CAs root certificates so we can download them and put to trusted list.
I can find one for ssl.com for example: https://www.ssl.com/how-to/install-ssl-com-ca-root-certificates/#ftoc-heading-4

But where can I find CA root certificate for TSA http://timestamp.acs.microsoft.com

The thing is we cannot make proper TSA request without having it's CA root certificate in local trusted list.
When the TSA can be done with any server from the list https://rfc3161.ai.moda/servers.json (thanks, that's quite nice), we need to have all root certificates in one place.

Hello! What can these servers be used for? Are they suitable for productive systems?
I am currently looking for a solution to sign log entries with some kind of trusted timestamp.

@Pique7 You can use them for anything, many folks are using https://rfc3161.ai.moda in production. We serve a few million requests per month now I think, with higher uptime than the majority of any single RFC3161 server (since we have automatic failovers).

How can i verify the timestamp? I get a response from a random server. But i also would like to verify this response locally. But for that i need CA and intermediate files i think. Could u also expose those/add them to the server list? I assume your backend has them in order to verify the response. Bonus for a example command :)

@chimmmpie I have made a script that extracts the .cer / .crt from a timestamping service

#!/usr/bin/env bash

set -o errexit
set -o nounset
set -o pipefail

# Check that we have the name of the TSA service as a first arg and the URL as a second arg
if [ "$#" -ne 2 ]; then
    echo "Illegal number of parameters"
    echo "Usage: $0 <TSA_URL> <TSA_NAME>"
    exit 1
fi

TSA_URL=$1
TSA_NAME=$2

echo "==> We are trying to get the TSA certificate from the following service : $TSA_NAME ($TSA_URL)"

echo "==> Sending a signature request..."
openssl rand 256 | openssl ts -query -data - -cert -sha256 | curl -s -S --data-binary @- "$TSA_URL" --header "Content-Type: application/timestamp-query" -o - -v > "$TSA_NAME.reply.tsr"

echo "==> Verifying the response..."
openssl ts -reply -text -in "$TSA_NAME.reply.tsr" || (echo "==> Verification failed :" && cat "$TSA_NAME.reply.tsr" && rm "$TSA_NAME.reply.tsr" && exit 1)

echo "==> Extracting the token..."
openssl ts -reply -in "$TSA_NAME.reply.tsr" -token_out -out "$TSA_NAME.token.tk"

echo "==> Extracting the TSA certificate..."
openssl pkcs7 -inform DER -in "$TSA_NAME.token.tk" -print_certs -outform PEM -out "$TSA_NAME.cer"

echo "==> Extracting the TSA certificate as a .crt..."
openssl x509 -inform PEM -in "$TSA_NAME.cer" -out "$TSA_NAME.crt"

rm "$TSA_NAME.reply.tsr" "$TSA_NAME.token.tk"

Call it like ./request_crt.sh http://timestamp.acs.microsoft.com/ microsoft to get everything in microsoft.crt

I have made a script that extracts the .cer / .crt from a timestamping service

Thanks, that is great!

Would it be possible to make version of the script that downloads all certs for servers provided by https://rfc3161.ai.moda/servers.json?

@chimmmpie I have made a script that extracts the .cer / .crt from a timestamping service

That looks interesting. But it would suggest to me that the cert is already in the response? Or does anyone think that some of the openssl commands will fetch it in the background?

The -certpart in openssl ts -query -data - -cert -sha256 asks the TSA to return its cert as well

@Pique7 You can use them for anything, many folks are using https://rfc3161.ai.moda in production. We serve a few million requests per month now I think, with higher uptime than the majority of any single RFC3161 server (since we have automatic failovers).

Thanks for your reply. Now I have another question:
The TSA certificate of my current test response has a validity of 10 years. I thinks that's a lot. But what can I do when the TSA certificate expires? Sorry if this question is too stupid or off-topic/misplaced.

The signature should still be considered valid (in my opinion), since it was signed within the original lifetime of the CA. It just can’t (or rather shouldn’t) be used for new signatures.

You shouldn’t have to do anything. All of the upstream servers for rfc3161.ai.moda should rollover to using a new certificates long before the current ones expire.

I you want to see the CA that was used in the response for your request, you can use asn1parse. Example:

openssl rand 512 | openssl ts -query -data - -cert -sha512 | curl -s -S --data-binary @- https://rfc3161.ai.moda -o - -v | openssl asn1parse -in /dev/stdin -inform DER -dump

Thanks for tip.

But once again: we are not able to generate a time stamp unless we have CA root certificate in the local "trusted" list.
Would it be possible to provide a list (URLs) of all available timestamping CA root certificates?

@vasekkral Sure. Note, these certificates do change over time.

This will dump the full certificate chain for all of the CAs. e.g. this is what my folder looks like after running the script:
