Hyunsik Choi commented on TAJO-495:
-----------------------------------
+1 for only digest
Both claims are all reasonable. I've considered it in many aspects for a while.
Regarding code maintenance and consistency of user experience, I prefer only
digest support.
Actually, other hashing functions (e.g., md5, sha512) are widely used too. For
example, if we support sha1 and do not support sha512, it may cause
inconsistency. It may be confuse for users.
