@validate-sdk/v2

Utility SDK for hashing, validation, encoding/decoding, and secure random generation.

Installation

npm install @validate-sdk/v2

or

yarn add @validate-sdk/v2

Usage

import {
  bs58,
  verifySha256String,
  sha256,
  sha512,
  md5,
  hashEquals,
  validate,
  encode,
  decode,
  generate,
} from "@validate-sdk/v2";

Hashing

const h1 = bs58("test");
const h2 = sha256("test");
const h3 = sha512("test");
const h4 = md5("test");

Verification

const ok = verifySha256String(
  "test",
  "9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08"
);

const safeEq = hashEquals("aabbcc", "aabbcc");

Validators

validate.sha256("9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08"); // true
validate.email("[email protected]"); // true
validate.ethAddress("0x742d35Cc6634C0532925a3b844Bc454e4438f44e"); // true
validate.uuid("550e8400-e29b-41d4-a716-446655440000"); // true
validate.strongPassword("Aa1@abcd"); // true

Available validators:

• sha256, sha512, md5, hex
• base64, base64url, base58, base32
• ethAddress, btcAddress, privateKeyHex
• jwt, uuid
• email, url, ipv4, ipv6
• alphanumeric, numeric, strongPassword, nonEmpty, length

Encode / Decode

const b64 = encode.base64("hello");
const b64url = encode.base64url("hello");
const hex = encode.hex("hello");

decode.base64(b64); // "hello"
decode.base64url(b64url); // "hello"
decode.hex(hex); // "hello"

Random generators

const rndHex = generate.hex(32);      // 32 random bytes as hex
const rndB64 = generate.base64(32);   // 32 random bytes as base64
const rndUuid = generate.uuid();      // UUID v4

API notes

• Hash functions accept string | Buffer.
• verifySha256String and hashEquals use timing-safe comparison semantics.
• Native addon is used when available; JS fallback is used otherwise.
