OpenSSL command line recipe for multi-public key file encryption. Any single private key paired to one of the public keys can decrypt the file.
#!/usr/bin/env bash
# Example of multiple key AES encryption for text files using the openssl v. 0.9.8+ command line utility
# Uses n public certs as key for MIME PKCS envelope, any individual private key can decrypt.
# If standard RSA ssh keys exist, these can be converted to public certs as well (and ssh keys can decrypt)
# To sign (and verify) the encrypted file, one of the private keys is required, see:
# for openssl smime examples
# or for cms utility (OpenSSL v. 1.0+)

Fork your own Gist

Fork your own Gist

This is a bookmarklet that adds a fully functional Fork button to your own Gist.

If a Fork button is already present in the page, this bookmarklet will set focus to it instead of adding another one.

The change is temporary and the button will disappear as soon as you navigate away from that Gist (clicking the Fork button does this for you as well).
