Hello all,

I would like to use encrypter service however it causes "forInvalidJSON('MalformedUTF-8...')" error.

I have configured the encryption key and left provider as OpenSSL in config. Any help appriciated.

Code:

Code:

$arr=['encryptedKey'=>service('encrypter')->encrypt('Deneme123')];

Error:

Code:

It is quite annoying that I never pass the encrypted non UTF-8 data to response. It is being handled in the model. However, I created my solution is by base64 encoding the encrypted data.

Maybe adding base64_encode output and pre base64_decode options would be a good idea to Encryption Interface.
