SHA 28 CHARACTER 40 CHARACTER ColdFusion 8

Using Hash expression with SHA according to docs it is to return a 28 character string. When I run this, it returns a 40 character string. From Documentation. SHA: Generates a 28-character string using the Secure Hash Standard SHA-1 algorithm specified by Nation Institute of Standards and Technology (NIST) FIPS-180-2. Is this a known issue, is there a work around?
