Module fcp_cryptoauth::cryptography [−] [src]

Modules

crypto_box	`crypto_box_curve25519xsalsa20poly1305` , a particular combination of Curve25519, Salsa20, and Poly1305 specified in Cryptography in `NaCl`.
scalarmult	`crypto_scalarmult_curve25519` specified in Cryptography in `NaCl`, Sections 2, 3, and 4. This function is conjectured to be strong. For background see Bernstein, "Curve25519: new Diffie-Hellman speed records," Lecture Notes in Computer Science 3958 (2006), 207–228, http://cr.yp.to/papers.html#curve25519.
sha256	`SHA-256`.

PrecomputedKey	Applications that send several messages to the same receiver can gain speed by splitting `seal()` into two steps, `precompute()` and `seal_precomputed()`. Similarly, applications that receive several messages from the same sender can gain speed by splitting `open()` into two steps, `precompute()` and `open_precomputed()`.
PublicKey	`PublicKey` for asymmetric authenticated encryption
SecretKey	`SecretKey` for asymmetric authenticated encryption

Number of bytes in a password digest.

gen_keypair	Randomly generates a secret key and a corresponding public key.
open_packet_end	unseals the concatenation of fields msg_auth_code, sender_encrypted_temp_pk, and encrypted_data of a packet. If authentication was successful, returns the sender's temp_pk and the data, unencrypted.
shared_secret_from_keys	AuthNone Hello packets: my_sk and their_pk are permanent keys Key packets: my_sk is permanent, their_pk is temporary data packets: my_sk and their_pk are temporary keys
shared_secret_from_password	Implements the fancy password hashing used by the FCP, decribed in paragraph 4 of https://github.com/fc00/spec/blob/10b349ab11/cryptoauth.md#hello-repeathello
