# OpenSSL::Cipher.key= (from ruby core) ### Implementation from Cipher --- cipher.key = string -> string --- Sets the cipher key. To generate a key, you should either use a secure random byte string or, if the key is to be derived from a password, you should rely on PBKDF2 functionality provided by OpenSSL::PKCS5. To generate a secure random-based key, Cipher#random_key may be used. Only call this method after calling Cipher#encrypt or Cipher#decrypt.
