Encrypt a string. Encode the output as Base64 with 80-character lines.

The Seed parameter is a Random.Seed, as created by Random.initialSeed

See Crypto.Strings.Crypt.encrypt for more options.

This shouldn't ever return an error, but since the key generation can possibly do so, it returns a Result instead of just (Ciphertext, randomState).

Testing function. Just returns the result with no random generator update.

Decrypt a string created with encrypt.

See Crypto.Strings.Crypt.decrypt for more options.

This can get errors if the ciphertext you pass in decrypts to something that isn't a UTF-8 string.
