Macro reference

hash_keygen

Fc9-comp-macro.png hash_keygen
Creates a secret key suitable for use with the hash_hash function. You must provide a 32 byte array for the key. 
Fc9-u8-icon.png - BYTE key
 
Fc9-void-icon.png - VOID Return


hash_with_key

Fc9-comp-macro.png hash_with_key
Creates a hash fingerprint of the data, using the given key. Returns 0 if successful. 
Fc9-u8-icon.png - BYTE hash
Buffer for the hash. Size >=32 makes it practically impossible for two messages to produce the same fingerprint. 
Fc9-u8-icon.png - BYTE data
The data buffer to be processed 
Fc9-u16-icon.png - UINT size
Byte count of the data to be processed 
Fc9-u8-icon.png - BYTE key
Key to be used 
Fc9-s16-icon.png - INT Return


hash_without_key

Fc9-comp-macro.png hash_without_key
Creates a hash fingerprint of the data, which will always have the same fingerprint, similar to the MD5 or SHA-1 Returns 0 if successful. 
Fc9-u8-icon.png - BYTE hash
Buffer for the hash. Size >=32 makes it practically impossible for two messages to produce the same fingerprint. 
Fc9-u8-icon.png - BYTE data
Data buffer to be processed 
Fc9-u16-icon.png - UINT size
Byte count of data to be processed 
Fc9-s16-icon.png - INT Return


init

Fc9-comp-macro.png init
Initialisation function. To be called at the very start of your program. 
Fc9-s16-icon.png - INT Return


secretbox_decrypt

Fc9-comp-macro.png secretbox_decrypt
Decrypts a message with a secret key. A single key is used both to encrypt/sign and verify/decrypt messages. For this reason, it is critical to keep the key confidential. Returns 0 on success. 
Fc9-u8-icon.png - BYTE message
Buffer for the decrypted message. Size must be at least length - 36 
Fc9-u16-icon.png - UINT length
The length (byte count) of the ciphertext 
Fc9-u16-icon.png - UINT ID
Message ID. Must match with the original message ID. Can be 0 
Fc9-u8-icon.png - BYTE key
The secret key 
Fc9-u8-icon.png - BYTE ciphertext
Buffer containing the ciphertext to be decrypted. 
Fc9-s16-icon.png - INT Return


secretbox_encrypt

Fc9-comp-macro.png secretbox_encrypt
Encrypts a message with a secret key. A single key is used both to encrypt/sign and verify/decrypt messages. For this reason, it is critical to keep the key confidential. Returns 0 on success. 
Fc9-u8-icon.png - BYTE message
Buffer containing the message to be encrypted. 
Fc9-u16-icon.png - UINT length
The length (byte count) of the message 
Fc9-u16-icon.png - UINT ID
Message ID. Can be 0 
Fc9-u8-icon.png - BYTE key
The secret key 
Fc9-u8-icon.png - BYTE ciphertext
Buffer for ciphertext output. Buffer size must be at least length + 36 
Fc9-s16-icon.png - INT Return


secretbox_keygen

Fc9-comp-macro.png secretbox_keygen
Creates a secret key suitable for use with the secretbox functions. You must provide a 32 byte array for the key. 
Fc9-u8-icon.png - BYTE key
 
Fc9-void-icon.png - VOID Return


sign_create

Fc9-comp-macro.png sign_create
Computes a signature for a message using the secret key. Returns 0 if successful. 
Fc9-u8-icon.png - BYTE signature
Buffer to receive the signature. Must be 64 bytes. 
Fc9-u8-icon.png - BYTE message
Buffer containing the data to sign 
Fc9-u16-icon.png - UINT message_size
Byte count of the message 
Fc9-u8-icon.png - BYTE secret_key
Secret/Private key to be used.Size is 64 bytes. 
Fc9-s16-icon.png - INT Return


sign_keygen

Fc9-comp-macro.png sign_keygen
Creates Private and Public key pair to sign and verify messages. Returns 0 if successful. 
Fc9-u8-icon.png - BYTE Secret
Buffer to receive the Private/Secret Key. Buffer size must be 64 bytes 
Fc9-u8-icon.png - BYTE Public
Buffer to receive the Public key. Buffer size must be 32 bytes 
Fc9-s16-icon.png - INT Return


sign_verify

Fc9-comp-macro.png sign_verify
Verify the signature of a mesasge using the public key. Returns 0 if successful. 
Fc9-u8-icon.png - BYTE signature
Buffer to receive the signature. Must be 64 bytes. 
Fc9-u8-icon.png - BYTE message
Buffer containing the data to sign 
Fc9-u16-icon.png - UINT message_size
Byte count of the message 
Fc9-u8-icon.png - BYTE public_key
Public key to be used.Size is 32 bytes. 
Fc9-s16-icon.png - INT Return
