Latest commit 3582e78 Sep 3, 2016 @drr00t committed on GitHub Merge pull request #11 from leandrogm/master
ref #4: Renamed some tests so we can now what they are supposed to be testing only by looking at the name. Added some comments inside tests to make it more clear. Remove duplications and not used stuff inside tests.

Public-key authenticated encryption (box)

Implements curve25519-xsalsa20-poly1305.

Byte[] CryptoBoxKeypair(Byte[] secretKey)

The CryptoBoxKeypair function randomly generates a secretKey and a corresponding public key. The secretKey array must have size equal to crypto_box_SECRETKEYBYTES

Byte[] CryptoBox(Byte[] message, Byte[] nonce, Byte[] publicKey, Byte[] secretKey)

The function encrypts and authenticates a message using the nonce, receiver´s publicKey and sender´s secretKey.

Byte[] CryptoBoxOpen(Byte[] cipheredMessage, Byte[] nonce, Byte[] publicKey, Byte[] secretKey)

The function verifies and decrypts a cipherMessage using the receiver's secretKey, the sender's publicKey, and a nonce.

Byte[] CryptoBoxBeforenm(Byte[] publicKey, Byte[] secretKey)

Applications that send several messages to the same receiver can gain speed by splitting CryptoBox into two steps, CryptoBoxBeforenm and CryptoBoxAfternm.

Byte[] CryptoBoxAfternm(Byte[] message, Byte[] nonce, Byte[] k)

Byte[] CryptoBoxOpenAfternm(Byte[] cipheredMessage, Byte[] nonce, Byte[] k)

Byte[] CryptoSignKeypair(Byte[] secretKey)

Byte[] CryptoSign(Byte[] message, Byte[] secretKey)

Byte[] CryptoSignOpen(Byte[] signedMessage, Byte[] publicKey)

Byte[] CryptoScalarmult(Byte[] n, Byte[] p)

Scalar multiplication is a curve25519 implementation.

Byte[] CryptoScalarmultBase(Byte[] n)

The CryptoScalarmultBase function computes the scalar product of a standard group element and an integer n
