Re: Not encryption but hashing

...cryptographic hash...

Yes, but that says something about the quality of the hash algorithm used. To qualify it must adhere to cryptographic principles. Actually, being a bit pedantic, SHA-1 lost the "cryptographic" qualification once collisions were detected and exploited.

It still has nothing to do with encryption or decryption because a hash is strictly one-way and encryption can be undone with decryption. You can never ever reverse a hash; the data is lost in the process of hashing and reduced to a hash value.
