dissector). Also, speed up ESP decryption in several ways: - store gcrypt_cipher_hd in the SA struct, rather than continually open, setkey and close for each PDU - don't convert the key string from ascii to hex each time - do it upon during update callback and keep - do the decryption in-place, avoiding the need to allocate, memcpy and free a separate buffer for encrypted data - when matching addresses, avoid doing a strlen until after we check whether or not we're matching against "*" Change-Id: Ibb66663ec21326351abc761be78a0d57f7797fa5 Reviewed-on: https://code.wireshark.org/review/1421 Reviewed-by: Anders Broman <a.broman58@gmail.com>
