Hi ! First of all, thank you for your time. Wan-Teh Chang a écrit : 2009/12/2 Gregory BELLIER : Examples : - For Camellia at the end of camellia_encryptCBC(CamelliaContext *cx, ...) : lastblock = output; memcpy(cx->iv, lastblock, CAMELLIA_BLOCK_SIZE); return SECSuccess; We save

Question about memcpy in operation mode for NSS

Hello ML, First of all, I'm not a crypto expert, that's why I ask this question which may appear obvious for some of you. I work on NSS and I've studied the CBC operation mode implementation for Camellia and SEED ciphers. I do understand how the CBC works but I don't understand why there is a

Where to compile ECC support conditionally (NSS_ENABLE_ECC) ?

Hello. Almost everywhere across NSS the ECC-specific executable code is compiled conditionally: #ifndef NSS_ENABLE_ECC /* ECC-specific executable code ... */ #endif ... but not everywhere. For example, seckey_ExtractPublicKey() @ cryptohi/seckey.c http://bonsai.mozilla.org/cvsblame.c
