Hash functions

Learn how to use and combine various hash functions in APL

The table summarizes the hash functions available in APL.

Name	Description
hash	Returns a signed integer hash for the input value.
hash_md5	Returns a MD5 hash value for the input value.
hash_sha1	Returns a sha1 hash value for the input value.
hash_sha256	Returns a SHA256 hash value for the input value.
hash_sha512	Returns a SHA512 hash value for the input value.

hash_md5

Returns an MD5 hash value for the input value.

Arguments

• source: The value to be hashed.

Returns

The MD5 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 255).

Examples

hash_md5(source)

['sample-http-logs']
| project md5_hash_value = hash_md5(content_type)

Run in Playground

• Result

{
  "md5_hash_value": "b980a9c041dbd33d5893fad65d33284b"
}

hash_sha1

Returns a SHA1 hash value for the input value.

Arguments

• source: The value to be hashed.

Returns

The sha1 hash value of the given scalar, encoded as a hex string

Examples

hash_sha1(source)

['sample-http-logs']
| project sha1_hash_value = hash_sha1(content_type)

Run in Playground

• Result

{
  "sha1_hash_value": "9f9af029585ba014e07cd3910ca976cf56160616"
}

hash_sha256

Returns a SHA256 hash value for the input value.

Arguments

• source: The value to be hashed.

Returns

The sha256 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 255).

Examples

hash_sha256(source)

['sample-http-logs']
| project sha256_hash_value = hash_sha256(content_type)

Run in Playground

• Result

{
  "sha256_hash_value": "bb4770ff4ac5b7d2be41a088cb27d8bcaad53b574b6f27941e8e48e9e10fc25a"
}

hash_sha512

Returns a SHA512 hash value for the input value.

Arguments

• source: The value to be hashed.

Returns

The sha512 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 511).

Examples

hash_sha512(source)

['sample-http-logs']
| project sha512_hash_value = hash_sha512(status)

Run in Playground

• Result

{
  "sha512_hash_value": "0878a61b503dd5a9fe9ea3545d6d3bd41c3b50a47f3594cb8bbab3e47558d68fc8fcc409cd0831e91afc4e609ef9da84e0696c50354ad86b25f2609efef6a834"
}
