WebFor example, before storing data, the user runs DBMS_CRYPTO.HASH against the stored data to create a hash value. On returning the stored data, the user can again run the hash function against it, using the same algorithm. If the second hash value is identical to the first one, then the data has not been altered. WebThe optional method argument lets you specify the name of the hash algorithm to be used. Valid algorithms are SHA1, SHA256, SHA384, SHA512, and MD5. If you omit this argument, then SHA1 is used. The function returns a RAW value.
