rsa encryption and decryption
I am working on a program that I use to encrypt and decrypt data. I am was not sure if I can encrypt and decrypt data, or just keys using the functions RSA_private_encrypt and RSA_public_decrypt. thanks... signature.asc Description: This is a digitally signed message part
Re: rsa encryption and decryption
Hello Mark, Yes, you an encrypt data using RSA. The only catch is size of the data to be encypted should be less than size of RSA keys. (i.e modulo n). -Prasanth - Original Message - From: Mark W.

I'm not sure how its best to fix this, but when I was looking it did seem to me to be clearly a bug in kerberos.

RE: rsa encryption and decryption
The size of the data must be less than the size of the modulus of the key. If it's a 1024-bit key (128 bytes) then the data must be at most 128 bytes. In fact, the data when viewed as a long integer must be of a smaller value than the modulus. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mark W.

0.9.6g problem with libpng and KDE 2.2-10 on RedHat 7.2 icons disappear
I recently downloaded openssl-0.9.6g.tar.gz and installed it on Redhat 7.2 using KDE 2.2-10. After I installed it, there was a dramatic problem with the icons in KDE. Some of the observable effects were: no redhat icon on the opening screen, an error that pops up upon login that states: Can't load docking tray icon, missing icons on the control panel, missing icons on the desktop, control center errors out. After restoring from tape all that seemed to make sense, I found that the problem is corrected by restoring the libpng??? files from the 0.9.6e version of openssl. There are 4 files I restore that correct the problem. I'm not sure they are all necessary. But I know it works if I restore these 4: cp -f /lib_copy/libpng.a /usr/lib cp -f /lib_copy/libpng.so /usr/lib cp -f /lib_copy/libpng.so.2 /usr/lib cp -f /lib_copy/libpng.so.2.1.0.12 /usr/lib You may already know about this problem. Please let me know if I'm onto a real problem, or I have a unique phantom. The md5sum checks out.

Re: 0.9.6g problem with libpng and KDE 2.2-10 on RedHat 7.2 icons disappear
This problem is reproducible. After installing openssl and openssh (which I always install from a shell script) the problem returns. When I install 0.9.6e I don't have this problem. If I correct the problem, install ssl/ssh the problem returns. restoring the files corrects the problem (every time).

I have found a problem with the way I was installing openssl. I had a broken copy of libpng??? being picked up and copied to the lib path. Sorry about troubling you with this problem. Thanks for the response. It got me digging deeper. On another note, what is the latest version of openssl that circumvents the slapper worm?

which version of openssl should use ?
Hello,all: I am delevloping a application using openssl, But I donn't know which version I shoulduse, Iconnected to ftp://ftp.openssl.org,and found there are two directory(sanpshot and source), should I use "/sanpshot/openssl-0.9.7-stable-SNAP-20020925.tar.gz" or "/source/openssl-0.9.6g.tar.gz"?Is "openssl-0.9.7-stable-SNAP-20020925.tar.gz" more stable and advance than "openssl-0.9.6g.tar.gz"?What does the words of "stable","SNAP" and "g" mean?
