Get Blob/Clob MD5 Hash

[martindsouza]

When storing files in a document type table would be good to have a MD5 of the file so we can find duplicates etc. This can currently be done with dbms_crypto but would be better if we can use a hash function that isn't restricted by default.

Could this be STANDARD_HASH?

@casajarm what do you mean by standard_hash ?
