getMD5

getMD5 Function

The getMD5 function generates an MD5 hash from a given input string using Node.js’ built-in crypto module. It supports configurable output encodings for flexible use in tracking and transformation scenarios.

---

Purpose

Use this.getMD5 to:

• Create a non-secure hash of a string (e.g., for deduplication, consistent keys)

• Generate lightweight identifiers or short checksums

• Obfuscate simple input values for non-critical use cases

⚠️ Note: MD5 is considered insecure for cryptographic purposes. Do not use it for hashing sensitive or security-critical data.

Function Definition

Property	Description
Function Name	this.getMD5
Type	function
Available In	Server-Side Variables
Returns	string (the hashed output)

---

Parameters

Parameter	Description	Type	Required	Example
input	The string value to hash	string		"secret"
encoding	The output encoding format ("hex", "base64", etc.)	string		"hex"

---

Supported Encodings

Refer to the Node.js crypto documentation for supported encodings. Common options:

• hex (recommended for readable output)

• base64

• latin1

---

Example Usage

async function() {
    let x = this.getMD5("secret", "hex");
    return x;
}

This example returns the MD5 hash of the string "secret" encoded as a hexadecimal string.

---

Use Cases

• Generate consistent hash keys for non-sensitive data

• Shorten string representations for logging or external IDs

• Create anonymized values when security is not a concern

---

Notes

• Always specify a valid encoding (no default is assumed).

• For secure hashing (e.g., SHA-256), use this.getHash instead.

• Output is deterministic: same input and encoding will always return the same result.

---

Summary

this.getMD5 is a quick and easy way to generate an MD5 hash in JENTIS server-side variables. While not suitable for cryptographic use, it is useful for creating lightweight, repeatable hashes for general-purpose tracking logic.
