For instance, any of the void DES_*_encrypt().? This cursory observation is also supported by a vendor application code such as: ?static void des_encrypt(char key1[8], char key2[8], char key3[8], char ivec[8], ???????????????? char *input, char *output, int len, ???????????????? int encrypt) ?{ ?? [snip] ??? DES_set_key(&des_key1, &schedule1); ??? DES_set_key(&des_key2, &schedule2); ??? DES_set_key(&des_key3, &schedule3); ??? DES_ede3_cbc_encrypt((unsigned char *)input, (unsigned char *)output, len, ???????????????????????? &schedule1, &schedule2, &schedule3, &des_ivec, ???????????????????????? encrypt); ?} This is basically why I'm wondering about how errors propagate in the OpenSSL library.
