SHAdigest (String function)

20-byte SHA digest (String class)

The SHAdigest intrinsic function returns the 20-byte (always) binary string that is the SHA digest of the method object string.

Syntax

%outString = string:SHAdigest

Syntax terms

%outString	A string variable to receive the SHA digest of the method object string.
string	The string to which the method is applied.

Usage notes

• SHA (Secure Hash Algorithm) is a set of cryptographic hashing functions; SHAdigest provides SHA-1, the most commonly used. A complete explanation of SHA hashing can easily be found on the internet.
• SHAdigest is available for use by Janus Soap or Janus Network Security customers.
• SHAdigest is available as of Sirius Mods version 7.3.

Examples

1. The 20-byte SHA hash of a string is typically expressed as a 40-digit hex value. In the following example, the output string from the SHAdigest method is converted to hex using the StringToHex intrinsic method:

   printText {'this is a simple test':shadigest:stringtohex}

   The result (displayed on two lines) is:

   'this is a simple test':shadigest:stringtohex is BC38AA2D6769639946806616C14AF0C69477AABE
