JavaScript

Hash (Digest) a String

Hash the bytes of a string.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var sb = new CkStringBuilder();

sb.Append("Hello World");

// Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
// Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.

// Get the SHA256 hash in hex
var sha256_hex = sb.GetHash("sha256","hex","utf-8");
console.log("SHA256: " + sha256_hex);

// Get the SHA384 hash in hex lowercase
var sha384_hex = sb.GetHash("sha384","hex_lower","utf-8");
console.log("SHA384: " + sha384_hex);

// Get the SHA512 hash in base64
var sha512_base64 = sb.GetHash("sha512","base64","utf-8");
console.log("SHA512: " + sha512_base64);

// Get the SHA1 hash in hex lowercase
var sha1_hex = sb.GetHash("sha1","hex_lower","utf-8");
console.log("SHA1: " + sha1_hex);

// Get the CRC8 digest in decimal
var crc8_decimal = sb.GetHash("crc8","decimal","utf-8");
console.log("CRC8: " + crc8_decimal);
