apr_sha256(8)   DB2 User Defined Function and Stored Procedure   apr_sha256(8)

NAME

       apr_sha256 - DB2 UDF and SP to generate an SHA256 hash

SYNOPSIS

       >>-APR_SHA256--(--expression--)--------------------------------><

       >>-APR_SHA256--(--expression--,--hash--)-----------------------><

DESCRIPTION

       SHA256   algorithm.  The  apr_sha256  routine  returns  the  identifier
       {SHA256} plus the base64 encoded sha256 hash.

       The argument can be a character string that is either a CHAR or VARCHAR
       not exceeding 4096 bytes.

       The  result of the function is CHAR(52). The result can be null; if the
       argument is null, the result is the null value.

EXAMPLES

       Example 1:

       Inserting the user test and the sha256 crypted clear  text  testpwd  to
       the table users.

       INSERT INTO USERS (username, password)
         VALUES ('test', apr_sha256('testpwd'))

       Example 2:

       SELECT apr_sha256('testpwd') FROM SYSIBM.SYSDUMMY1

       1
