I seriously doubt that this is a aes-ni-related problem, try running charon with the environment-variable OPENSSL_ia32cap set, such that bit #57 is cleared [1] (should be the value ~0x200000000000000). > > strongswan version I am using is 4.3.6 and openssl version openssl-1.0.0. > > I ran gdb on the core file, it is pointing to the below point > > > #4 0x00007fabd3eee1b7 in EVP_CIPHER_CTX_set_key_length > (c=0x7fabcc99e8b0, keylen=16) at evp_enc.c:520 > 520evp_enc.c: No such file or directory. > in evp_enc.c > (gdb) p *c > $1 = {cipher = 0x0, engine = 0x0, encrypt = 1, buf_len = 0, oiv = '\000' > <repeats 15 times>, iv = '\000' <repeats 15 times>, buf = '\000' <repeats 31 > times>, num = 0, > app_data = 0x0, > key_len = 0, flags = 256, cipher_data = 0x0, final_used = 0, block_mask > = 0, final = '\000' <repeats 31 times>} A little more context (as in backtrace: '(gdb) help bt') would certainly help! But I'm guessing it leads somewhere to [2], which as you can see, calls EVP_CIPHER_CTX_set_key_length, regardless of EVP_CipherInit_ex's return code. Martin fixed this in [3] which is first available with strongswan 5.0.2, so maybe you check this version out. However: my guess is, that openssl has problems dealing with the cipher, use gdb to print *this->cipher from openssl_crypt.c to shed some more light on this. Btw: which openssl-1.0.0 version are you using: [d-n] are available)?
