security.Digest.CreateDigestString

Creates a SHA1 digest from the given string.

Syntax

security.Digest.CreateDigestString(
   toDigest STRING,
   randomBase64 STRING )
  RETURNS STRING
  1. toDigest defines the password to be digested.
  2. randomBase64 defines a random string in Base64.

Usage

Use this method to compute the SHA1 digest from the string in toDigest and an optional random Base64 form string, and return it in a string encoded in Base64 form.

The random value must be a valid Base64 string. You typically generate this value with the security.RandomGenerator.CreateRandomString() method.

In case of error, the method throws an exception and sets the status variable. Depending on the error, a human-readable description of the problem is available in the sqlca.sqlerrm register. See Error handling in GWS calls (status).

Example

DEFINE password, digest STRING
...
LET digest =
    security.Digest.CreateDigestString(
       password,
       security.RandomGenerator.CreateRandomString(16) )
