Simple AES-encryption And -decryption Using The OpenSSL-library
def aes(m,k,t)
(aes = OpenSSL::Cipher::Cipher.new('aes-256-cbc').send(m)).key = Digest::SHA256.digest(k)
aes.update(t) << aes.final
end
def encrypt(key, text)
aes(:encrypt, key, text)
end
def decrypt(key, text)
aes(:decrypt, key, text)
end
if $0 == __FILE__
p "text" == decrypt("key", encrypt("key", "text"))
end
