How to compute all attributes of RSA private key from modulus and private exponent?

Hello Ihave got one question: Does exist some way how to compute all attributes of private key from modulus and private exponent? I think as public exponent, prime1, prime2, exp1, exp2... Thanks -- View this message in context: http://www.nabble.com/How-to-compute-all-attributes-of-RSA-privat

Any alternative to rsautl for signing ("signaturing") ?

In the man page for rsautl, OpenSSL 0.9.7l in Mac OS X, I read this "Note" at the bottom: "rsautl because it uses the RSA algorithm directly can only be used to sign or verify small pieces of data." That seems to imply that there is a better alternative to rsautl for signing. What is it?

Re: En/Decrypt Mismatch: Command-Line Tool vs. Perl's Crypt::OpenSSL

Well, I got this working, although I there are several things that don't seem to work they way they should. Short summary: Must use perl function private_encrypt() instead of sign(), even though, to generate the same signature, the command-line tool must use -sign. Must use the SHA1 dige

Re: X.509] Certificate Generation without PoP

What you're saying is this: 1) You know who the principal is (and therefore the CN to stick into your certificate), due to your pre-existing protocol. 2) You know what the public key is, also due to your pre-existing protocol. 3) You've already verified the proof of possession of the private key (

SSL_session_reused api

Hi All I have been using this API to dump in my statistics logs whether the SSL session is reused or not in a windows openSSL based client. Everything was good till i was using 9.7e. The session reuse works fine and the logs were correctly showing session reused as 1 and sniffer traces reconfirm

Re: X.509] Certificate Generation without PoP

Thanks for your answer, David. Let me explain some more of my problem. The reason for not wanting to make a "usual" CSR is that my client is not able to send the CSR to the server (CA) app. In fact, I am extending an existing communication protocol, where I keep the already defined message types a

Re: any reference to different certificate versions

X.509 refers to the certificate version. 0 == version 1, 1 == version 2, 2 == version 3. Version 1 certificates have no means for any extensions. Version 2 certificates are CRLs. Version 3 certificates are the current norm, and most likely what you want. The best reference currently is RFC5280,

any reference to different certificate versions

Hi, I can set a certificate version using function X509_set_version(). Can some one give me a reference to different certificate versions that are available and the significance of each version number. -Thanks and Regards, -Sanjith.

what is the significance of iteration number on ASN1_INTEGER_set()

Hi, I couldnt get a documentation for ASN1_INTEGER_set(). Just want to know the significance of the second argument of this function. What is the difference when I provide 0 and PKCS12_DEFAULT_ITER for it? Thanks and Regards -Sanjith
