      int SVC_CompareSHA1( const void* decedHash,
                             const void* digest );

## Arguments

decedHash | SHA-1 value 1
digest | SHA-1 value 2

## Return Values

Returns TRUE if the SHA-1 values match after comparison. Returns FALSE if they do not match, or if NULL was passed to one of the arguments.

## Description
