Keuntae Park commented on TAJO-495:
-----------------------------------
It works fine as it passes 'mvn clean install' successfully.
However, how about implementing more generalized function 'digest' like
PostgreSQL?
digest(text, type), where type can be one of md5, sha1, sha224, sha256, sha384
and sha512.
(http://www.postgresql.org/docs/9.3/static/pgcrypto.html)
> Implement sha1(text)
