.UTIL COMPUTE HASH

This subroutine computes the SHA-2 hash value for the given string. APPX 5.4.5 & higher only.

Usage:

*     PASS         <hash value returned>      FIELD            SHARE? Y
*     PASS         <hash type>                FIELD            SHARE? N
*     PASS         <Data to hash>             FIELD            SHARE? N
*     GOSUB    --- .UTIL COMPUTE HASH
      *        Check for errors
*     IF       --- .UTIL COMPUTE HASH         NE

Description:

This subroutine computes the SHA-2 hash value for the given string. The first 2 parameters are required and if any required parameters are missing, the subroutine will CANCEL.

<hash value returned> is the computed value returned. This must be passed with Share="Y" to return a value. It should be an alpha field at least 64 or 128 bytes in length, depending on the <hash type> requested (Required).

<hash type> is the type of hash value you want returned (Required):

• B for a 64 byte binary value
• UC for a 128 byte readable value, upper case
• LC for a 128 byte readable value, lower case
