Type Alias esp_idf_sys::esp_rc4_skip_t

pub type esp_rc4_skip_t = Option<unsafe extern "C" fn(key: *const c_uchar, keylen: c_uint, skip: c_uint, data: *mut c_uchar, data_len: c_uint) -> c_int>;

@brief XOR RC4 stream callback function to given data with skip-stream-start

@param key RC4 key @param keylen RC4 key length @param skip number of bytes to skip from the beginning of the RC4 stream @param data data to be XOR’ed with RC4 stream @param data_len buf length Returns: 0 on success, -1 on failure

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.
