"Signature did not match the certificate request"

Hi!!! I'm running openssl-0.9.7e patched for ERACOM I'm getting the following error message: "Signature did not match the certificate request" when I excecute the following command: openssl x509 -req -in cli/test.certreq -CA ca/CA_cert.pem -engine ERACOM -CAkey ca/CA.keylink > cli/test_cert.pe

BIO_READ and BASE64 Decode

I am trying to decode a base64 encoded string. There appears to be something wrong. The read tells me that I have read 21 which is correct, but my output buffer has nothing in it. Any suggestions on what is wrong with the code. Thanks in Advance!   int main {    char *sBase64[21]  // this

Re: ECB, CBC, CFB, OFB, and when and where you would use them.

Sorry Victor, Im not explaining it very well. Let me try again. What we need to do is to protect data from the point of view of ensuring that if the media it is on be that a hard drive, tape, or optical disk is encrypted. For our system that is best done by encrypting each file on a file by file

linking error

I'm attempting to use OpenSSL to talk to an SSL server across campus. I obtained example OpenSSL client code written in C from http://www.rtfm.com/openssl-examples and modified this code slightly to fit my needs. ssl_stuff.o is my version of the file that one time included the "main" program

RE: ECB, CBC, CFB, OFB, and when and where you would use them.

Why not encrypt the file using PKCS#7 enveloped or signed and enveloped data. 3DES-CBC or AES for date encryption, key encryption using intended recipient public key, authentication using RSA singer public key? If you need non-expanding data encryption using symmetric cipher, look at EAS in CTR m

Re: ECB, CBC, CFB, OFB, and when and where you would use them.

Ok that is good info. What about just doing file level encryption. As an example you have a disk with a bunch of files, and it is only those files you would want encrypted, and the issue is more a confidentiality is required / media loss issue then a tamper issue? We are looking to use AES-256 fo

Sorry I forgot to state that it is to encrypt file data on storage devices such as disks, and tapes. I agree with your statement of appearance, but im trying to get the folks the resources that they need to do it correctly. They are currently in the design, and spec phase of this, so now is the ti

I wonder if some one could point me to some high level document that would describe where, and when you would use ECB, CBC, CFB, OFB modes. I have some developers that are trying to include encryption into some code, and there seems to be some confusion among them. -- David Gianndrea Senior Netw

How do I restart the same SSL session after calling SSL_shutdown()?

Hi! II want to restart the same SSL session after calling SSL_shutdown(). I tried the following but it got stuck at SSL_connect(). I wonder if I can do either of the following on the client: 1) Call SSL_shutdown() but then reuse the same SSL object for a later SSL_connect(). or 2) Call SSL_shu
