If CA is TRUE then an optional pathlen name followed by a nonnegative value can be included. extension is not present or cannot be parsed. public_key ca_cert. It can be used to display certificate information, convert certificates to various forms, sign certificate requests like a "mini CA" or edit certificate trust settings. "0.emailAddress=Ema... OpenSSL "req -new -reqexts" - Test CSR V3 Extensions. The following sections describe the syntax of each supported extension. The first value is CA followed by TRUE or FALSE. And "issuer" value is required. The character encoding of explicitText can be specified by prefixing the value with UTF8, BMP, or VISIBLE followed by colon. A CA certificate can be used to sign other certificate. This is a multi-valued extension that supports several types of name identifier, including email (an email address), URI (a uniform resource indicator), DNS (a DNS domain name), RID (a registered ID: OBJECT IDENTIFIER), IP (an IP address), dirName (a distinguished name), and otherName. I need a certificate to connect my facebook-profile and my hotmail. Another one is called AlternativeNames (Subject Alternative Name), which allows the certificate to be used under more then just one, single common name. x509_extensions = usr_cert This defines the section in the file to find the x509v3 extensions to be added to signed certificates. Home ; grep::cpan ; Recent ... Return a hash of Extensions indexed by OID or name. You can use x.509 v3 extensions options when using OpenSSL "req -new" command to generate a CSR (Certificate Signing Request). This is a multi-valued extension whose values can be either a name-value pair using the same form as subject alternative name or a single value specifying the section name containing all the distribution point values. These examples are extracted from open source projects. Netscape Comment (nsComment) is a string extension containing a comment which will be displayed when the certificate is viewed in some browsers. Advantages.

"openssl req -new -x509 -nodes -set_serial 2005100101 -keyout ftpd.pem -out ftpd.pem -days 365". Maybe you can use that command (and "openssl x509 -in ftpd.pem -noout -text | head -5") to see if dave_thompson_085's comment is the key. Extreme care should be taken to ensure that the data is formatted correctly for the given extension type.
