typedef XNTLM_DES_KS; void xntlm_deskey (XNTLM_DES_KS ks, unsigned char *key, int decrypt); void xntlm_des (XNTLM_DES_KS ks, unsigned char block[8]);
These routines implement DES encryption and decryption. They are here primarly for xntlm-internal use, but can also be used by other code.
typedef guint32 XNTLM_DES_KS[16][2];
This represents a DES key schedule. After initializing it with xntlm_deskey(), you can then pass it to xntlm_des() as many time as you need.
void xntlm_deskey (XNTLM_DES_KS ks, unsigned char *key, int decrypt);
Sets up ks based on key. You must call this to initialize the key schedule before calling xntlm_des().
ks : | key schedule to fill in |
key : | the encryption key |
decrypt : | 0 for encryption, 1 for decryption |
void xntlm_des (XNTLM_DES_KS ks, unsigned char block[8]);
DES encrypts/decrypts (according to ks) a single block in ECB mode.
ks : | the key schedule to use |
block : | the block of data to encrypt or decrypt |
