SHA-1 hash
ID sha1hash
DatatypeNot PIIidentifier
Digest of the SHA-1 hash function (160 bits), used for example as a Git object id or a file checksum. SHA-1 is no longer considered collision-resistant. It is written as 40 hexadecimal digits. SHA-1 and RIPEMD-160 digests have the same length, so the value alone does not tell them apart: use the field name or context.
