The encrypted output is not a NULL terminated string so strlen will not work.
EVP_DecryptUpdate(amp;ctx, (unsigned char *)plaintextz, amp;out_len,
(unsigned char *)ciphertext, strlen(ciphertext));
Use the length output from the encryption part.
Thank you very much
Hi,
What protocol are you using?
What I mean is application layer protocol. But since in your example, you're
using your own protocol,
why not send both length and data.
Example.
4 byte len field0..2^32-1 data field
Then in you receiving end, do recv 4 bytes, get length, and recv until
received

Don't you know how much data you've read that you're about to decrypt?
in your code template, you showed the sendign routine doing...
nread = recv(sock, buffer, 25, 0);
isn't the recieving routine doing somethign similar? well, nread would
be the length you need, no?

Hi there, I've been searching for a solution to this problem
for 3 days. I'm using the ruby openssl module to encrypt/decrypt
small amounts of data with 2048 bit mod key.
I've created an x509 certificate using the sample code provided in
mkcert.c. The certificate works fine in doing the basic SSL handshake
and I can use i2d_x509 to extract the bytes and then convert it back
to d2i_x509 and print it using X509_print_fp. For some reason though
if I try to convert it
Hi,
I am trying to verify whether a ca signed certificate is revoked.
Openssl verify option requires following parameters:
- cert : A ca signed certificate to be verified.
- cafile: FilePath to ca certificate used to sign the certificate (cert).
