The argument must have the form of: config key/value pairs (i.e. The -noout option allows to avoid the display of the key in base 64 format. openssl x509 -fingerprint -noout -in self-signed-certificate.pem. OpenSSL can also be seen as a complicated piece of software with many options that are often compounded by the myriad of ways to configure and provision SSL certificates. HI, How to add Email address E=test.example.com. # To use this configuration file with the "-extfile" option of the # "openssl x509" utility, name here the section containing the # X.509v3 extensions to use: # extensions = # (Alternatively, use a configuration file that has only # X.509v3 extensions in its main [= default] section.) openssl genrsa -des3 -out ca.key 2048 openssl req -new -key ca.key -out ca.csr openssl x509 -req -days 3650 -in ca.csr -signkey ca.key -out ca.crt. The openssl command-line options are as follows: s_client: The s_client command implements a generic SSL/TLS client which connects to a remote host using SSL/TLS. The -x509 option specifies that you want a self-signed certificate rather than a certificate request. We can print our new certificate information and details with the -noout and -text options like below. Anstatt die Option ca zu verwenden, versuchen Sie die Option x509 mit -req.

The openssl program is a command line tool for using the various cryptography functions of OpenSSL's crypto library from the shell. If you were a CA company, this shows a very naive example of how you could issue new certificates. If you do not wish to be prompted for anything, you can supply all the information on the command line. Der Default-Algorithmus ist SHA-1. not sure if there is a way. But most options are documented in in the man pages of the subcommands they relate to, and its hard to get a full picture of how the config file works. This comment has been minimized. GIG says: Reply. If you don't want your private key encrypting with a password, add the -nodes option. OpenSSL will generate a temporary CSR for the purpose of gathering information to associate with the certificate, so you will have to answer the prompts per usual. – Piotr Zierhoffer 28 sep. 12 2012-09-28 10:40:23. $ openssl x509 -req -days 365 -in t1.csr -signkey key.pem -out t1.crt Self Sign CSR Print X.509 Certificate Information and Details .
