Method: OpenSSL::HMAC.digest

Defined in:
lib/openssl/hmac.rb

.digest(digest, key, data) ⇒ Object

:call-seq:

HMAC.digest(digest, key, data) -> aString

Returns the authentication code as a binary string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.digest('SHA1', key, data)
#=> "\xDE|\x9B\x85\xB8\xB7\x8A\xA6\xBC\x8Az6\xF7\n\x90p\x1C\x9D\xB4\xD9"
