getHash FunctionThe getHash function generates a hashed string from a given input using the Node.js crypto library. It supports configurable hashing algorithms and output encodings.
Use this function to:
Create hashed versions of identifiers or tokens
Generate consistent anonymized values (e.g., hashed IPs, emails)
Integrate hash-based logic into tracking or enrichment flows
Function Name
this.getHash
Type
function
Available In
Server-Side Variables
Returns
string (the hashed value of the input)
input
The input string to be hashed
string
"secret"
algorithm
The hashing algorithm to use (e.g., "sha256", "md5", etc.)
string
"sha256"
encoding
The output format of the hash ("hex", "base64", etc.)
string
"hex"
Default Encoding:
"hex"if not specified
See the official Node.js Crypto documentation for a full list of supported algorithms and encodings.
Common choices:
Algorithms: sha256, sha1, md5, sha512
Encodings: hex, base64, latin1
This example returns a SHA-256 hash of the string "secret" encoded in hexadecimal.
Generate anonymized keys (e.g., hashed IP or user ID)
Create checksum or verification values
Store secure reference identifiers without exposing raw input
Match identifiers across systems using shared hashing rules
This function uses Node.js' built-in crypto.createHash behind the scenes.
Output is deterministic: same input → same hash.
Make sure the chosen algorithm and encoding match your system requirements.
Do not use md5 or sha1 for security-critical applications — these are considered weak.
this.getHash is a flexible and secure way to generate hashed values in JENTIS server-side variables. Whether you’re anonymizing personal data or aligning IDs across systems, this function allows full control over the hashing algorithm and encoding.
