// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

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.
View multi_key_crypto.sh
#!/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:
# http://www.openssl.org/docs/apps/smime.html#EXAMPLES for openssl smime examples
# or http://www.openssl.org/docs/apps/cms.html#EXAMPLES for cms utility (OpenSSL v. 1.0+)
