The API would provide a low-level interface to create and/or manage public keys and private keys for hashing, digital signature generation and verification and encryption and decryption for use with web applications. The Web Cryptography API could be used for a wide range of uses, including: Providing authentication for users and services
NaCl (Networking and Cryptography Library, pronounced "salt") is a public domain, high-speed software library for cryptography. [2]NaCl was created by the mathematician and programmer Daniel J. Bernstein, who is best known for the creation of qmail and Curve25519.
Because many users re-use passwords for multiple sites, the use of a salt is an important component of overall web application security. [14] Some additional references for using a salt to secure password hashes in specific languages or libraries (PHP, the .NET libraries, etc.) can be found in the external links section below.
JSON Web Token (JWT, suggested pronunciation / dʒ ɒ t /, same as the word "jot" [1]) is a proposed Internet standard for creating data with optional signature and/or optional encryption whose payload holds JSON that asserts some number of claims. The tokens are signed either using a private secret or a public/private key.
PKCS #8 is one of the family of standards called Public-Key Cryptography Standards (PKCS) created by RSA Laboratories. The latest version, 1.2, is available as RFC 5208. [1] The PKCS #8 private key may be encrypted with a passphrase using one of the PKCS #5 standards defined in RFC 2898, [2] which supports multiple encryption schemes.
Public-key encryption was first described in a secret document in 1973; [15] beforehand, all encryption schemes were symmetric-key (also called private-key). [16]: 478 Although published subsequently, the work of Diffie and Hellman was published in a journal with a large readership, and the value of the methodology was explicitly described. [17]
OS2IP - Octet String to Integer Primitive - Interprets a sequence of bytes as a non-negative integer; RSAEP - RSA Encryption Primitive - Encrypts a message using a public key; RSADP - RSA Decryption Primitive - Decrypts ciphertext using a private key; RSASP1 - RSA Signature Primitive 1 - Creates a signature over a message using a private key
One brief comment in the text mentions, but does not mandate, the possibility of simply using the ASCII encoded value of a character string: "Finally, the key argument is a secret encryption key, which can be a user-chosen password of up to 56 bytes (including a terminating zero byte when the key is an ASCII string)."
