Method: PKCS11::Session#decrypt

Defined in:

lib/pkcs11/session.rb

#decrypt(mechanism, key, data = nil) {|PKCS11::Session::Cipher| ... } ⇒ String

Convenience method for the #C_DecryptInit, #C_DecryptUpdate, #C_DecryptFinal call flow.

Examples:

Decrypt data previously encrypted with a RSA pulic key

plaintext2 = session.decrypt( :RSA_PKCS, rsa_priv_key, cryptogram)

Parameters:

• mechanism (Hash, Symbol, Integer, PKCS11::CK_MECHANISM) —

  used mechanism

• key (PKCS11::Object) —

  used key

• data (String) (defaults to: nil) —

  data to decrypt

Yields:

• (PKCS11::Session::Cipher) —

  Cipher object for processing data parts

Returns:

• (String) —

  the final part of the encryption operation.
