256-bit SHA-2 digest (String class)
[Introduced in Model 204 7.6]
The SHA256digest intrinsic function returns the 32-byte (always) binary string that is the SHA-256 digest of the method object string.
Syntax
%outString = string:SHA256digest
Syntax terms
| %outString | A string variable to receive the SHA-256 digest of the method object string. |
|---|---|
| string | The string to which the method is applied. |
Usage notes
- The the SHA-256 digest algorithm is also available as an option of the DigestAlgorithm enumeration.
- SHA256digest is available for use by Model 204 V7.6 or greater or by Janus Network Security customers.
Examples
The 32-byte SHA-256 hash of a string is typically expressed as a 64-digit hex value. In the following example, the output string from the SHA256digest method is converted to hex using the StringToHex intrinsic method:
printText {'testing':sha256digest:stringtohex}
The result is:
365B9CF22DF4D98F00DC41325B822E1FF2872FB046C09BF5669404850EA0BE0B
