Function Block CRYPT_HMAC
The Function Block CRYPT_HMAC calculates the HMAC hash of a string according to the configuration.
Input DATA
Defines the string from which the hash is calculated.
Input KEY
Defines the key used for calculation.
Input ALGO
Defines the algorithm to be used to generate the hash value. If no value is specified, the algorithm sha256 is used. The following algorithms are supported:
- md2
- md4
- md5
- sha1
- sha224
- sha256
- sha384
- sha512
- ripemd128
- ripemd160
- ripemd256
- ripemd320

Input BINARY
If the input is true, a binary output is generated. This corresponds to post-processing using Function Block HEX2BIN. However, it is much more efficient.
Output HASH
The checksum is output at the output as a hexadecimal string or binary value.
