Re: EVP errors!

This is not working... I have just done a hex dump and the key still bears no resemblence to the key reported by the command lineis it because i have version 0.9.8k of the SDK and 0.9.8g of the command line? Dr. Stephen Henson wrote: On Mon, Aug 10, 2009, MusicAndy wrote: The Key

GOT IT WORKING!! WOOHOO! (open up the champagne!) Now I just need to get it working with salt (maybe with a tequilla and lemon) MusicAndy wrote: This is not working... I have just done a hex dump and the key still bears no resemblence to the key reported by the command lineis it

Des3 and the salt option

Hi folks. Well almost got things to work the way i want to :jumping: One more question. The salt format of a file in DES3. I notice that the file that has been encrypted with the use of salt has Salted__ followed by bytes of data. If i read this from a stream, do i strip the Salted__ part off

Re: Des3 and the salt option

Also, do I need to strip out these salt characters in my input buffer? The reason i ask is that it is decrypting most of the file but leaves this at the top (if you see the rest of this string is an xml header) ›³žšb+pÙ\ªú6*ýÑ­.Ë€ÆÑErsion=1.0 encoding=UTF-8? MusicAndy wrote: Hi folks.

Certificate verification through Callback

Hi All I am using SSL_CTX_set_cert_verify_callback(ctx, callback, (void *)arg) API to register the callback function for certificate verification. However I need to set the mode (SSL_VERIFY_PEER) for SSL Context. I am using below code to set mode and callback function. Is it right way of doing

Is Openssl vulnerable to Null-Prefix Attacks?

Help!!!

Hi, I am new to OpenSSL and I was going through the following post. http://marc.info/?l=openssl-usersm=112774769218757w=2 Well I want achieve a similar thing. I want to reduce the per connection memory usage of OpenSSL. Now, I am facing a few issues : *i) Connecting a client to the server.*

Noticed something in the openssl-1.0.0 20090811 SNAPshot

First Time I have seem Cannot find path to openssl/engines/ . In FreeBSD-7.2 and64 it is a show stopper. In the old BSDI BSD/OS 4.3.X just create directory and away you go. Suggestion: Can the path to openssl/engines/ point ot path to openssl/lib/ after all only .so's are being installed. --

Re: Is Openssl vulnerable to Null-Prefix Attacks?

Hi, I read the PDF and my first question would be. How is this relevant to openssl, since it is normally only used for creating and signing certificates It is more up to a brower to do the proper checking; That's why the PDF states While many SSL/TLS implemntations fall victim to this, Mozila's

RE: Is Openssl vulnerable to Null-Prefix Attacks?

When I read through the null prefix attack paper I took it to mean that browser and certificate vendors were not doing an adequate job of verifying domain names. There's nothing inherently wrong with using counted strings (actually that is a step in the right direction IMHO). The problem is

Redux and Resolved: Deconstructing OASIS Web Services Security SOAP Messages with OpenSSL utilities

For some reason I didn't get any newsfeeds after re-subscribing, so I can't really post to my earlier inquiry. I've figured this out. 1) Convert Key's CipherValue from base64-to-binary 2) rsautl against the Key's CipherValue.bin - gives binary version of the decoded key  (uses the private key)
