HMAC with SHA256

See more Encryption Examples

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. Tcl

load ./chilkat.dll

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

set crypt [new_CkCrypt2]

# The output will be Hex, so set the EncodingMode:
CkCrypt2_put_EncodingMode $crypt "hex"

# Set the hash algorithm:
# Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
CkCrypt2_put_HashAlgorithm $crypt "sha256"
CkCrypt2_put_MacAlgorithm $crypt "hmac"

# Set the HMAC key:
CkCrypt2_SetMacKeyEncoded $crypt "The_API_Secret" "ascii"
set mac [CkCrypt2_macStringENC $crypt "The quick brown fox jumps over the lazy dog"]
puts "$mac"

delete_CkCrypt2 $crypt
