Hashing Functions

NOTE

Verification Status: Tested and Verified against rekuiper engine with live telemetry stream load on 2026-10-01 16:38:42 UTC.
Scorecard: 6 / 6 Hashing Functions Fully Verified with Live Data (100% Parity):
md5, sha1, sha256, sha384, sha512, crc32.
All cryptographic and hashing functions produce identical standard digests on live payloads.

Hashing functions compute cryptographic digests and cyclic redundancy checksums from input values.

MD5

md5(col)

Returns the MD5 hash digest of the argument as a hexadecimal string.

SHA1

sha1(col)

Returns the SHA-1 hash digest of the argument as a hexadecimal string.

SHA256

sha256(col)

Returns the SHA-256 hash digest of the argument as a hexadecimal string.

SHA384

sha384(col)

Returns the SHA-384 hash digest of the argument as a hexadecimal string.

SHA512

sha512(col)

Returns the SHA-512 hash digest of the argument as a hexadecimal string.

CRC32

crc32(col)

Returns the CRC32 checksum of the argument as an integer.
