Bcrypto provides you with a consistent interface across Node.js and the browser. It is implemented as a [Node.js addon][addon] for C libraries [libtorsion][libtorsion] and [libsecp256k1][libsecp256k1] with corresponding implementations in JavaScript. ## Usage ```js const rng = require('bcrypto/lib/random'); const entropy = rng.randomBytes(32); const Hash256 = require('bcrypto/lib/hash256'); const digest = Hash256.digest(Buffer.alloc(32, 0xaa)); ``` ## API See the `./lib` directory for available modules and APIs. ## Implementations | | nodejs (linux) | nodejs (macos) | nodejs (win) | browser | | :--------------------------- |:------------------| :-----------------|:------------------|:--------| | aead | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | aes | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | bcrypt | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | blake2b{160,256,384,512} | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | blake2s{128,160,224,256} | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | bn | js w/ bigint | js w/ bigint | js w/ bigint | js | | chacha20 | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | cshake{128,256} | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | ctr-drbg | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | dsa | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | eb2k | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | ecies | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | ed25519 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | ed448 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | gost94 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | hash160 | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | hash256 | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | hash-drbg | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | hkdf | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | hmac-drbg | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | keccak/sha3{224,256,384,512} | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | kmac{128,256} | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | md{2,4,5} | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | md5sha1 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | merkle | js | js | js | js | | mrkl | js | js | js | js | | murmur3 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | p{192,224,256,384,521} | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | pbkdf2 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | pgp | js | js | js | js | | poly1305 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | random | c (openssl²) | c (openssl²) | c (openssl²) | js³ | | rc4 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | ripemd160 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | rsa | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | rsaies | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | salsa20 | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | schnorr | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | scrypt | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | secp256k1 | c (libsecp256k1²) | c (libsecp256k1²) | c (libsecp256k1²) | js | | sha1 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | sha{224,256,384,512} | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | shake{128,256} | c (libtorsion¹) | c (libtorsion¹) | c (libtorsion) | js | | siphash | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | ssh | js | js | js | js | | whirlpool | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | x25519 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | | x448 | c (libtorsion) | c (libtorsion) | c (libtorsion) | js | ### Footnotes 1. with x86-64 assembly 2. optionally with libtorsion 3. using the webcrypto api ## Contribution and License Agreement If you contribute code to this project, you are implicitly allowing your code to be distributed under the MIT license.
