Hi! I tried to compile your code, but the following include files are missing (or not included in MacOS, Linux and openSSL distribution): - portable.h - exception.h - ltscrypto.h - logger.h Can you tell me where to find these? Thank you! Regards, Harald Am 18.05.2007 um 22:51 schrieb

Harald, They are specific to my system. Let me edit the file for you to do exactly what you need. It will give you a model to work from. Which would you like me to do: AES, 3DES or BLOWFISH? Peace, Charles Harald Latzko wrote: Hi! I tried to compile your code, but the following include

Hi! AES256-CBC and 3DES-EDE-CBC-3key would be the algorithm used by me. (AES with a higher priority). Thank you in advance, Harald Am 19.05.2007 um 18:43 schrieb Chaz.: Harald, They are specific to my system. Let me edit the file for you to do exactly what you need. It will give you a

Here are examples, from my code, of both 3DES and AES. Any questions, ask away. Chaz. Harald Latzko wrote: Hi! Do you have a solution for deryption of big files using des3 and/or aes256, too? The openSSL command line smime utility eats up all my memory and crashes after a while...

Hi, all I have encrypted the file with the manpage example (blowfish), and then decrypt it. It will be fine if I try some small files, however, when I test some big files (e.g.: 100M), the decryption will not work. Is there anybody can suggest me an available way to do big file encryption and

Hi! I use for big file encryption the new stream support of openSSL 0.9.9, it works perfectly. For decryption (and signature verification), the stream support is not implemented yet. So we have to wait until it's implemented, or find another solution. If you have found another way to do
