SHA1
Hashes the given string or binary data using the so-called secure hash algorithm, version 1. SHA1 has been deprecated as a means of securely signing data. It is present in SingleStore DB mainly for backwards compatibility and for systems which require a “good enough” hashing function and can tolerate collisions. For a more secure hash function, see [SHA2].
