bare-crypto

Cryptographic primitives for JavaScript.

npm i bare-crypto

Usage

const crypto = require('bare-crypto')

const hash = crypto.createHash('sha256')

hash.update('Hello, world!')

const digest = hash.digest('hex')

console.log(digest)

API

const hash = createHash(algorithm[, options])

Create a new Hash instance with the specified algorithm and options. The options are passed to new Transform().

const buffer = randomBytes(size)

Generate cryptographically secure random bytes.

randomBytes(size, callback)

Generate cryptographically secure random bytes, asynchronously providing the result in callback. The callback signature is callback(err, buffer).

buffer = randomFill(buffer[, offset][, size])

Fill a buffer with cryptographically secure random bytes.

randomFill(buffer[, offset][, size], callback)

Fill a buffer with cryptographically secure random bytes, asynchronously providing the result in callback. The callback signature is callback(err, buffer)

constants.hash

The supported hash algorithms.

Constant	Description
MD5	A widely-used 128-bit hash function, now considered insecure due to vulnerabilities to collision attacks. Still fast but not recommended for security-sensitive purposes.
SHA1	A 160-bit hash function, stronger than MD5 but also broken by collision attacks. Deprecated for most cryptographic uses due to security vulnerabilities.
SHA256	Part of the SHA-2 family, this 256-bit hash function is widely used and considered secure for most applications. Slower than MD5 and SHA1 but much more secure.
SHA512	Another member of the SHA-2 family, this 512-bit hash function offers greater security than SHA256 but is slower and produces larger hashes. Suitable for high-security environments.
BLAKE2B256	A fast, secure alternative to SHA-2 designed for efficiency, producing a 256-bit hash. It is optimized for performance while maintaining strong cryptographic security.
