Function Documentation

void rc4 (  u8 *  buf, size_t  len, const u8 *  key, size_t  key_len )

XOR RC4 stream to given data. Parameters: buf  data to be XOR'ed with RC4 stream len  buf length key  RC4 key key_len  RC4 key length Generate RC4 pseudo random stream for the given key and XOR this with the data buffer to perform RC4 encryption/decryption. Definition at line 86 of file rc4.c. Here is the call graph for this function:

void rc4_skip (  const u8 *  key, size_t  keylen, size_t  skip, u8 *  data, size_t  data_len )

XOR RC4 stream to given data with skip-stream-start. Parameters: key  RC4 key keylen  RC4 key length skip  number of bytes to skip from the beginning of the RC4 stream data  data to be XOR'ed with RC4 stream data_len  buf length Generate RC4 pseudo random stream for the given key, skip beginning of the stream, and XOR the end result with the data buffer to perform RC4 encryption/decryption. Definition at line 36 of file rc4.c.
