HMAC SHA-1 to Match RFC 2022 Test VectorsDemonstrates using Chilkat in Ruby to computer HMAC SHA-1 message authentication codes to match the test vectors given by RFC 2202. require 'chilkat' crypt = Chilkat::CkCrypt2.new() # Any string argument automatically begins the 30-day trial. success = crypt.UnlockComponent("30-day trial") if (success != true) print "Crypt component unlock failed" + "\n" exit end # The output will be Hex, so set the EncodingMode: crypt.put_EncodingMode("hex") # Set the hash algorithm: # Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval crypt.put_HashAlgorithm("sha-1") # Set the HMAC key: crypt.SetHmacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex") mac = crypt.hmacStringENC("Hi There") print mac + "\n"; crypt.SetHmacKeyEncoded("Jefe","us-ascii") mac = crypt.hmacStringENC("what do ya want for nothing?") print mac + "\n"; |
