This includes changing the definition of * N8_SSLTLSPacket_t, adding SSLTLS_*_OFFSET defines, and adding * macros for SSLTLS_EXTRACT_* and SSLTLS_SET_*. * 05/30/01 bac Changed structure comments. Changed type of the verify_p in * DecryptVerify. * 05/22/01 bac Changed data definition in N8_SSLTLSPacket_t. Changed * interfaces to SSLTLSDecrypt and SSLTLSAuthenticate to take and * return packets instead buffers. Added prototypes for * N8_GetHashLength and N8_ComputeEncryptedLength. * 05/18/01 bac Converted to N8_xMALLOC and N8_xFREE * 05/18/01 bac Fixed N8_SSLTLSEncryptAuthenticate prototype to match new * API. * 05/02/01 bac Original version. ****************************************************************************/ #ifndef N8_SSLTLS_H #define N8_SSLTLS_H #include "n8_pub_packet.h" #include "n8_packet.h" #define N8_DES_BLOCK_MULTIPLE 8 #define N8_DES_MD5_MIN_LENGTH 24 #define N8_DES_SHA1_MIN_LENGTH 24 #define N8_ARC4_MD5_MIN_LENGTH 16 #define N8_ARC4_SHA1_MIN_LENGTH 20 #define SSLTLS_TYPE_OFFSET 0 #define SSLTLS_VERSION_OFFSET 1 #define SSLTLS_LENGTH_OFFSET 3 #define SSLTLS_DATA_OFFSET 5 #define SSLTLS_HEADER_LEN 5 #define SSLTLS_EXTRACT_TYPE(PACKET_P) (const uint8_t) (PACKET_P[SSLTLS_TYPE_OFFSET]) #define SSLTLS_EXTRACT_VERSION(PACKET_P) ntohs(*((const uint16_t *) &PACKET_P[SSLTLS_VERSION_OFFSET])) #define SSLTLS_EXTRACT_LENGTH(PACKET_P) ntohs(*((const uint16_t *) &PACKET_P[SSLTLS_LENGTH_OFFSET])) #define SSLTLS_SET_TYPE(PACKET_P, VALUE) PACKET_P[SSLTLS_TYPE_OFFSET] = (VALUE) #define SSLTLS_SET_VERSION(PACKET_P, VALUE) *((uint16_t *) &PACKET_P[SSLTLS_VERSION_OFFSET]) = htons((VALUE)) #define SSLTLS_SET_LENGTH(PACKET_P, VALUE) *((uint16_t *) &PACKET_P[SSLTLS_LENGTH_OFFSET]) = htons((VALUE)) /* * SSL/TLS content types as defined by the protocol.
