It is derived from SHA-1, with assorted changes intended to increase its security. It produces a 160-bit output.

HAS-160 is used in the same way as SHA-1. First it divides input in blocks of 512 bits each and pads the final block. A digest function updates the intermediate hash value by processing the input blocks in turn.

The message digest algorithm consists of 80 rounds."; + this.inputType = "ArrayBuffer"; + this.outputType = "string"; + this.args = []; + } + + /** + * @param {ArrayBuffer} input + * @param {Object[]} args + * @returns {string} + */ + run(input, args) { + return runHash("has160", input); + } + +} + +export default HAS160; diff --git a/src/core/operations/HMAC.mjs b/src/core/operations/HMAC.mjs new file mode 100644 index 00000000..e29656ce --- /dev/null +++ b/src/core/operations/HMAC.mjs @@ -0,0 +1,87 @@ +/** + * @author n1474335 [n1474335@gmail.com] + * @copyright Crown Copyright 2016 + * @license Apache-2.0 + */ + +import Operation from "../Operation"; +import Utils from "../Utils"; +import CryptoApi from "crypto-api/src/crypto-api"; + +/** + * HMAC operation + */ +class HMAC extends Operation { + + /** + * HMAC constructor + */ + constructor() { + super(); + + this.name = "HMAC"; + this.module = "Hashing"; + this.description = "Keyed-Hash Message Authentication Codes (HMAC) are a mechanism for message authentication using cryptographic hash functions."; + this.inputType = "ArrayBuffer"; + this.outputType = "string"; + this.args = [ + { + "name": "Key", + "type": "binaryString", + "value": "" + }, + { + "name": "Hashing function", + "type": "option", + "value": [ + "MD2", + "MD4", + "MD5", + "SHA0", + "SHA1", + "SHA224", + "SHA256", + "SHA384", + "SHA512", + "SHA512/224", + "SHA512/256", + "RIPEMD128", + "RIPEMD160", + "RIPEMD256", + "RIPEMD320", + "HAS160", + "Whirlpool", + "Whirlpool-0", + "Whirlpool-T", + "Snefru" + ] + } + ]; + } + + /** + * @param {ArrayBuffer} input + * @param {Object[]} args + * @returns {string} + */ + run(input, args) { + const key = args[0], + hashFunc = args[1].toLowerCase(), + msg = Utils.arrayBufferToStr(input, false), + hasher = CryptoApi.getHasher(hashFunc); + + // Horrible shim to fix constructor bug.

Depth: If an operation appears to match the data, it will be run and the result will be analysed further. This argument controls the maximum number of levels of recursion.

Extensive language support: At each stage, the relative byte frequencies of the data will be compared to average frequencies for a number of languages.
