Function Documentation

int tlsv1_record_change_read_cipher ( struct tlsv1_record_layer rl  ) 

tlsv1_record_change_read_cipher - TLS record layer: Change read cipher : Pointer to TLS record layer data Returns: 0 on success (cipher changed), -1 on failure

This function changes TLS record layer to use the new cipher suite configured with tlsv1_record_set_cipher_suite() for reading.

Definition at line 111 of file tlsv1_record.c.

int tlsv1_record_change_write_cipher ( struct tlsv1_record_layer rl  ) 

tlsv1_record_change_write_cipher - TLS record layer: Change write cipher : Pointer to TLS record layer data Returns: 0 on success (cipher changed), -1 on failure

This function changes TLS record layer to use the new cipher suite configured with tlsv1_record_set_cipher_suite() for writing.

Definition at line 77 of file tlsv1_record.c.

int tlsv1_record_receive ( struct tlsv1_record_layer rl,
const u8 in_data,
size_t  in_len,
u8 out_data,
size_t *  out_len,
u8 alert 
)

tlsv1_record_receive - TLS record layer: Process a received message : Pointer to TLS record layer data : Received data : Length of the received data : Buffer for output data (must be at least as long as in_data) : Set to maximum out_data length by caller; used to return the length of the used data : Buffer for returning an alert value on failure Returns: 0 on success, -1 on failure

This function decrypts the received message, verifies HMAC and TLS record layer header.

Definition at line 245 of file tlsv1_record.c.

int tlsv1_record_send ( struct tlsv1_record_layer rl,
u8  content_type,
u8 buf,
size_t  buf_size,
size_t  payload_len,
size_t *  out_len 
)

tlsv1_record_send - TLS record layer: Send a message : Pointer to TLS record layer data : Content type (TLS_CONTENT_TYPE_*) : Buffer to send (with TLS_RECORD_HEADER_LEN octets reserved in the beginning for record layer to fill in; payload filled in after this and extra space in the end for HMAC). : Maximum buf size : Length of the payload : Buffer for returning the used buf length Returns: 0 on success, -1 on failure

This function fills in the TLS record layer header, adds HMAC, and encrypts the data using the current write cipher.

Definition at line 152 of file tlsv1_record.c.

int tlsv1_record_set_cipher_suite ( struct tlsv1_record_layer rl,
u16  cipher_suite 
)

tlsv1_record_set_cipher_suite - TLS record layer: Set cipher suite : Pointer to TLS record layer data : New cipher suite Returns: 0 on success, -1 on failure

This function is used to prepare TLS record layer for cipher suite change. tlsv1_record_change_write_cipher() and tlsv1_record_change_read_cipher() functions can then be used to change the currently used ciphers.
