Hello, Parametr "-nosalt" is not used in this case.
I have attached my test code, to use this example save file aes_enc.c and
execute:
# gcc -Wall -pedantic -o aes_enc -lcrypto aes_enc.c
# ./aes_enc | od -x
0000000 e61f b8eb c202 6df8 4cc4 631e 4bf2 dedd
0000020
# ./aes_enc > enc.bin
# openssl aes-256-cbc -in enc.bin -K
000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F -iv
000102030405060708090A0B0C0D0E0F -d
marek
I other words, when you prepare source buffer for excryption you shoud
manualy pad this data.
Best regards,
