Memory buffers, PKCS7_sign, etc

I have the following program that runs without error but for some reason appears to write a truncated or invalid signed message: -- #include #include #include #include #include #include #include #include static void info (const char *str) { fprintf (stderr, "info: %s\n", str); } stat

General Encryption Question

I'm using the aes-256-cbc encryption method. Lets say I'm encrypting something like an xml file that obviously has known pieces -- the nodes, etc. Does this weaken the encryption at all from the perspective of brute forcing the message? More generally if the attacker knows, for instance, the fir

Re: Decryption does not yield the same as Encryption

I am encrypting prior to encoding. The encryption coding is below. Also, I tried the coding changes below that were recommended and got the same results. Any other ideas? buff = malloc(bptr->length + 1); buff[bptr->length]=0; void encrypt(char *inbuf, char *outbuf, int blklen, char *ke

Re: Decryption does not yield the same as Encryption

At first glance, there's a thing: 1) your code shows a classic mistake in a wicked way: that is OpenSSL works on *data*, not on *C strings*. (C strings are NUL-sentinel terminated, data is just data, no terminator. Since you extract the amount of *data* written to the BIO mem sink (bptr->length),

Hi, I am new to OpenSSL, and am using an AMCC Sequoia target with a PPC440EPx on it, and ELDK 4.2 (containing OpenSSL 9.8b). Various functions such as PEM_read_PUBKEY() fail, and I see: Trace/breakpoint trap This same error message is printed if I run various commands at the "OpenSSL>"
