Hello Folks, I am new to OpenSSl and I have a few questions: 1) When I use the command "openssl genrsa -out key", what format is the key written in. Since I didn't specify encryption, does OpenSSL still write the key in PEM encoded format? In general, does a PEM encoded message always begin with the PEM header such as Proc-Type, Content-Domain etc. 2) When I use the command "openssl req -new -key key -text", what are prime1, prime2, exponent1, exponent2 etc. How are they related to the RSA algorithm, in which the n and the e are the public key, and the d is the private key. 3) When I use the command "openssl req -new -key key text", what is the use of the challenge password? Is it the key for encryption using DES CBC mode. BTW are there documents out there that I can read about this related stuffs. Thanks in advance! -Moses ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
