This new release brings updates to Universal Storage, query optimization, and usability that you won’t want to miss.

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].

Syntax

SHA1(plaintext)
SHA(plaintext)

Arguments

  • plaintext: the data to hash.

Return Type

40 lower case hexadecimal digits corresponding to the 160-bit binary hash value.
