I come from Laravel background where the following interface exists ( docs if you really want to see more ): # example value make by `php artisan key:generate` # ENV["APL_KEY"] = "base64:dTOymAUpqvF/2tOxnQdakYHuL66HlmkElovGwumCiPE=" struct SimpleEncrypt def initialize( @key : String = ENV["APP…

I found https://github.com/dscottboggs/crypher , maybe its code would be useful

https://github.com/didactic-drunk/sodium.cr seems good candidate for your use-case. Especially the example https://github.com/didactic-drunk/sodium.cr#secret-key-encryption

You can check my simple cli app: https://github.com/Geo-7/openssl_sample

Hello, # Encrypt *data* def cipher_encrypt(data) : IO::Memory cipher = OpenSSL::Cipher.new("aes-256-cbc") cipher.encrypt cipher.key = App.cfg.cipher_key cipher.iv = App.cfg.cipher_iv cipher.update data encrypted = cipher.final IO::Memory.new(encrypted) end # Decr…

Forget my example above. I made a more practical and reliable shard : https://github.com/Nicolab/crystal-crypt . require "crypt" require "crypt/crypter" require "crypt/random" data = "super secret data" secret = Crypt.random_string(32) crypter = Crypt::Crypter.new(secret) # Data encrypted encrypte…

A shard is not necessary for Bcrypt, it is easy enough with the stdlib. For OpenSSL, I can agree not so much. I hope the API will be revisited and more type safe after the 1.0.
