sodium-up

Convenience wrapper around sodium-universal

Usage

var sodium = require('sodium-up')

var random = sodium.randombytes_buf(Buffer.allocUnsafe(16))

API

WIP

See sodium-native for complete documentation.

sodium.randombytes_*

var output = sodium.randombytes_buf(output)

output can either be a Buffer or integer length. Will return output

sodium.crypto_sign_*

Constants:

• sodium.crypto_sign_SEEDBYTES
• sodium.crypto_sign_PUBLICKEYBYTES
• sodium.crypto_sign_SECRETKEYBYTES
• sodium.crypto_sign_BYTES

var {publicKey, secretKey} = crypto_sign_seed_keypair([publicKey, secretKey], seed)

publicKey and secretKey are optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_sign_PUBLICKEYBYTES and sodium.crypto_sign_SECRETKEYBYTES length. Will return and object with {publicKey, secretKey}

var {publicKey, secretKey} = crypto_sign_keypair([publicKey, secretKey])

publicKey and secretKey are optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_sign_PUBLICKEYBYTES and sodium.crypto_sign_SECRETKEYBYTES length. Will return and object with {publicKey, secretKey}

var signedMessage = crypto_sign([signedMessage], message, secretKey)

signedMessage is optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_sign_BYTES length. Will return signedMessage

var boolOrBuf = crypto_sign_open([message], signedMessage, publicKey)

message is optional, but can be Buffer or integer length. Defaults to Buffer of signedMessage.length - sodium.crypto_sign_BYTES length. Will return false if the signature is invalid or message otherwise

var signature = crypto_sign_detached([signature], message, secretKey)

signature is optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_sign_BYTES length. Will return signature

var bool = crypto_sign_verify_detached(signature, message, publicKey)

Alias to sodium-native#crypto_sign_verify_detached

sodium.crypto_generichash_*

Constants:

• sodium.crypto_generichash_PRIMITIVE
• sodium.crypto_generichash_BYTES_MIN
• sodium.crypto_generichash_BYTES_MAX
• sodium.crypto_generichash_BYTES
• sodium.crypto_generichash_KEYBYTES_MIN
• sodium.crypto_generichash_KEYBYTES_MAX
• sodium.crypto_generichash_KEYBYTES

var output = crypto_generichash([output], input, [key])

output is optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_generichash_BYTES length. Will return output

Examples of input permutations:

sodium.crypto_generichash(input)
sodium.crypto_generichash(input, key)
sodium.crypto_generichash(output, input, null)
sodium.crypto_generichash(null, input, key)
sodium.crypto_generichash(null, input, null)

var instance = crypto_generichash_instance([key], [outputLength])

sodium-native#crypto_generichash_instance wrapped in an object so .update() and .final() can be overridden.

var instance = instance.update(input)

Will return instance for easy chaining

var output = instance.final([output])

output is optional, but can be Buffer of outputLength or longer. Defaults to Buffer of outputLength length. Will return output

sodium.crypto_pwhash_*

Constants:

• sodium.crypto_pwhash_ALG_DEFAULT
• sodium.crypto_pwhash_BYTES_MIN
• sodium.crypto_pwhash_BYTES_MAX
• sodium.crypto_pwhash_PASSWD_MIN
• sodium.crypto_pwhash_PASSWD_MAX
• sodium.crypto_pwhash_SALTBYTES
• sodium.crypto_pwhash_STRBYTES
• sodium.crypto_pwhash_STRPREFIX
• sodium.crypto_pwhash_OPSLIMIT_MIN
• sodium.crypto_pwhash_OPSLIMIT_MAX
• sodium.crypto_pwhash_MEMLIMIT_MIN
• sodium.crypto_pwhash_MEMLIMIT_MAX
• sodium.crypto_pwhash_OPSLIMIT_INTERACTIVE
• sodium.crypto_pwhash_MEMLIMIT_INTERACTIVE
• sodium.crypto_pwhash_OPSLIMIT_MODERATE
• sodium.crypto_pwhash_MEMLIMIT_MODERATE
• sodium.crypto_pwhash_OPSLIMIT_SENSITIVE
• sodium.crypto_pwhash_MEMLIMIT_SENSITIVE
• sodium.crypto_pwhash_PRIMITIVE

var output = sodium.crypto_pwhash([output], password, salt, opslimit, memlimit, algorithm)

output can either be a Buffer or integer length. Will return output

var output = sodium.crypto_pwhash_str([output], password, opslimit, memlimit)

output is optional, but can be Buffer or integer length. Defaults to Buffer of sodium.crypto_pwhash_STRBYTES length. Will return output

var bool = sodium.crypto_pwhash_str_verify(str, password)

Alias to sodium-native#crypto_pwhash_str_verify
