If you want to give only Travis-CI access to a private key or secret file in your repository, you will need to encrypt it, but rather than storing the entire encrypted file in an environment variable, just store the a secret password in a secure environment variable that you will use to encrypt and decrypt your private key file. The encryption o…
# generate your private key, put the public key on the server you will be connecting to
ssh-keygen -t rsa -f ./my_key
# generate the password/secret you will store encrypted in the .travis.yml and use to encrypt your private key
cat /dev/urandom | head -c 10000 | openssl sha1 > ./secret
# encrypt your private key using your secret password
openssl aes-256-cbc -pass "file:./secret" -in ./my_key -out ./my_key.enc -a

quick-and-dirty simulator of PAN GlobalProtect server
#!/usr/bin/env python3
# This is used for testing openconnect's (
# handling of the atrocious XML+JavaScript mess used for
# authenticating to a PAN GlobalProtect VPN.
# Requires a recent version of Flask and Python 3.x, and a server.pem
# Should be fairly easy to tweak to fit various authentication scenarios.

Juniper VPN logging script for mitmproxy v4.0.4
# Run like this with mitmproxy v4.0.4:
# mitmdump --script --tcp-hosts JUNIPER.SERVER.COM
# It will dump the TCP flows with the server in a raw-ish format to /tmp/TCPFlow*,
# and will replace the MD5 hash of the "real" server certificate with that of the
# MITM'ed server certificate (as provided to the client) anywhere it appears in the
# TCP flows' content.

Exhaustive solution to
Consider 15 standard pool balls arranged in a triangle (7 solids, 7 stripes, one 8-ball).
- Solids are all equivalent to each other
- Stripes are all equivalent to each other
- Robot can perform one of three operations: rotate 120° CW, rotate 120° CCW, swap 2 balls

Make a working RSA token from seed, expiration date, and serial number
# Takes SN, EXPIRATION, and SEED environment variables
# (SEED must be 32 hex digits) and converts them to
# an RSA SecurID token in CTF format.
# Requires:
# stoken >=v0.9
# perl5
# base64

Fake server for RSA SecurID token generation (see
#!/usr/bin/env python3
# Needs: Python 3.5+, Flask, PyCryptoDome
# server.pem, rsapubkey.pem + rsaprivkey.pem (1024-bit) in the current directory
# What it does:
# Pretends to be the "CT-KIP" web service ( that
# RSA SecurID Token for Windows v5.0.x talks to to set up a new token, using an
# authentication code.
