So I see a lot of posts on HN that alude to difficulties when developing apps with encrypted comms. Do most languages not already have encrypt/decrypt libraries to leverage. E.g I would expect to be able to find a public-private (RSA) implementation in most languages, where I could do somthing like:
String encryptedMessage = RSAEncryptor.encrypt(publicKey, message)
Is this not the case? Do such libs have bugs?
