GT2/GT2-iOS/node_modules/bcrypt-pbkdf

Port of the OpenBSD bcrypt_pbkdf function to pure Javascript. npm-ified version of [Devi Mandiri's port] (https://github.com/devi/tmp/blob/master/js/bcrypt_pbkdf.js), with some minor performance improvements. The code is copied verbatim (and un-styled) from Devi's work.

This product includes software developed by Niels Provos.

API

bcrypt_pbkdf.pbkdf(pass, passlen, salt, saltlen, key, keylen, rounds)

Derive a cryptographic key of arbitrary length from a given password and salt, using the OpenBSD bcrypt_pbkdf function. This is a combination of Blowfish and SHA-512.

See this article for further information.

Parameters:

• pass, a Uint8Array of length passlen
• passlen, an integer Number
• salt, a Uint8Array of length saltlen
• saltlen, an integer Number
• key, a Uint8Array of length keylen, will be filled with output
• keylen, an integer Number
• rounds, an integer Number, number of rounds of the PBKDF to run

bcrypt_pbkdf.hash(sha2pass, sha2salt, out)

Calculate a Blowfish hash, given SHA2-512 output of a password and salt. Used as part of the inner round function in the PBKDF.

Parameters:

• sha2pass, a Uint8Array of length 64
• sha2salt, a Uint8Array of length 64
• out, a Uint8Array of length 32, will be filled with output
