OpenSSL::Engine#cipher

This returns an OpenSSL::Cipher by name, if it is available in this engine.

A EngineError will be raised if the cipher is unavailable.

e = OpenSSL::Engine.by_id("openssl")
 => #<OpenSSL::Engine id="openssl" name="Software engine support">
e.cipher("RC4")
 => #<OpenSSL::Cipher:0x007fc5cacc3048>

OpenSSL::Engine#digest

This returns an OpenSSL::Digest by name.

Will raise an EngineError if the digest is unavailable.

e = OpenSSL::Engine.by_id("openssl")
  #=> #<OpenSSL::Engine id="openssl" name="Software engine support">
e.digest("SHA1")
  #=> #<OpenSSL::Digest: da39a3ee5e6b4b0d3255bfef95601890afd80709>
e.digest("zomg")
  #=> OpenSSL::Engine::EngineError: no such digest `zomg'

OpenSSL::HMAC::digest

Returns the authentication code as a binary string. The digest parameter must be an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'
digest = OpenSSL::Digest.new('sha1')

hmac = OpenSSL::HMAC.digest(digest, key, data)
#=> "\xDE|\x9B\x85\xB8\xB7\x8A\xA6\xBC\x8Az6\xF7\n\x90p\x1C\x9D\xB4\xD9"

OpenSSL::HMAC::hexdigest

Returns the authentication code as a hex-encoded string. The digest parameter must be an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'
digest = OpenSSL::Digest.new('sha1')

hmac = OpenSSL::HMAC.hexdigest(digest, key, data)
#=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"

OpenSSL::HMAC#digest

Returns the authentication code an instance represents as a binary string.

Example

instance = OpenSSL::HMAC.new('key', OpenSSL::Digest.new('sha1'))
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f
instance.digest
#=> "\xF4+\xB0\xEE\xB0\x18\xEB\xBDE\x97\xAEr\x13q\x1E\xC6\a`\x84?"
