DESCryptoServiceProvider encryption and OpenSSL decrypt

Hello everyone. I'm using .NET to encrypt a file using DES. I'm using this: DESCryptoServiceProvider, CryptoTransform and CryptoStream Anyone knows how to use OpenSSL to decrypt the file? Thanks in advance. Best Regards.

Option -issuer_hash vs signature validation with -CAfile?

Hi there, I received an SMIME certificate and want to know the correct filename to use in the command openssl smime -verify -CAfile filename... In my particular example, openssl x509 -in smime.pem -issuer_hash -noout results in 9ec3a561. However, if I use that certificate (available as

Upgrading the key size in OpenSSL certificate

Hi All, We are required to upgrade the sizes of private/public key pairs to 3072 bits from 1024 bits. We have two main data structures, X509Stack and PKCS7. We fill these two structures at the initialization by reading the PEM files on disk. During the upgrade process, I pick the X509stack and

.RSA conversion

Dear All, I have a certificate with a .rsa extension. On googling I found that this is a pkcs7 format using MD5 with RSA. Now my question is, is there a way to convert it to openssl specifics and handle?? I want to read it in say PEM.. thanks

Re: Upgrading the key size in OpenSSL certificate

Thanks Viktor for your quick response. Even I am contesting the unnecessary usage of 3072 bit sized key. Surprisingly, in the given scenario, if I write this line of code before modifying the certificate it works like a charm. pkcs7 = PKCS7_dup(pkcs7); Below is the flow of APIs 1) pkcs7 =

.deb packages for 1.0.0?

Has anyone seen .deb packages for openssl 1.0.0? I took a quick stab at converting the 0.9.8 debian files, but I ran into a lot of problems and it takes a long time to debug. -- Chris Bare ch...@bareflix.com __ OpenSSL Project

EC domain params instead of the OID in the pkcs8 key file?

Hi, using the openssl tool, we generated an Elliptic Curve key pair and put it into a pkcs8 file: 0 48: SEQUENCE { 32: INTEGER 0 6 48: SEQUENCE { 86: OBJECT IDENTIFIER ecPublicKey (1 2 840 10045 2 1) 176: OBJECT IDENTIFIER '1 2 840 10045 3 1 7'

Config file being ignored

Here is an example of what happens if I run it from the command line interface: openssl OpenSSL engine dynamic -pre SO_PATH:/usr/local/lib/engines/engine_pkcs11.so -pre ID:pkcs11 -pre LIST_ADD:1 -pre LOAD -pre MODULE_PATH:/usr/lib64/opensc-pkcs11.so (dynamic) Dynamic engine loading support

Ok I am getting closer. I can get the engine to load now with this (better) config file openssl_conf = openssl_def [openssl_def] engines = engine_section [engine_section] pkcs11 = pkcs11_section [pkcs11_section] engine_id = pkcs11 dynamic_path = /usr/local/lib/engines/engine_pkcs11.so
