class OpenSSL::HMAC
Overview
Allows computing Hash-based Message Authentication Code (HMAC).
It is a type of message authentication code (MAC) involving a hash function in combination with a key.
HMAC can be used to verify the integrity of a message as well as the authenticity.
See also RFC2104.

openssl/hmac.crClass Method Summary
-
.digest(algorithm : OpenSSL::Algorithm, key, data) : Bytes
Returns the HMAC digest of data using the secret key.
-
.hexdigest(algorithm : OpenSSL::Algorithm, key, data) : String
Returns the HMAC digest of data using the secret key, formatted as a hexadecimal string.

Class Method Detail
Returns the HMAC digest of data using the secret key.
It may contain non-ASCII bytes, including NUL bytes.
algorithm specifies which OpenSSL::Algorithm
is to be used.
Returns the HMAC digest of data using the secret key, formatted as a hexadecimal string. This is necessary to safely transfer the digest where binary messages are not allowed.
