hash helper

Tom Santiago
Updated

Use {{hash}} to apply a cryptographic hash (e.g., MD5, SHA-256) to a string or field value, returning the result in the specified encoding format.

Usage

{{hash algorithm encoding field}}

  • algorithm: A supported hashing algorithm (e.g., "md5", "sha256", "sha1").

  • encoding: The output format of the hashed value ("hex" or "base64" are most common).

  • field: The actual data (literal or field reference) to be hashed.

Note

Examples

  1. Hash a record field with MD5 and base64 

    {{hash "md5" "base64" record.name}}

    If record.name is "Bob", this outputs an MD5 hash of "Bob" encoded in base64.

  2. SHA-256 hash in hex 

    {{hash "sha256" "hex" "HelloWorld"}}

    Produces a hex-encoded SHA-256 hash of the string "HelloWorld".

Tip

  • Choose stronger algorithms (e.g., SHA-256) for better security over weaker ones like MD5.

  • Ensure the input field is a string or can be converted to one.

  • The hash output is irreversible—if you need keyed signatures (authentication), see the hmac helper instead.
