The pathlen parameter specifies the maximum number of CAs that can appear below this one in a chain. Other extensions of this type are: nsBaseUrl, nsRevocationUrl, nsCaRevocationUrl, nsRenewalUrl, nsCaPolicyUrl and nsSslServerName. X509 V3 extensions options in the configuration file allows you to add extension properties into x.509 v3 certificate when you use OpenSSL commands to generate CSR and self-signed certificates. Otherwise, the value must be a hex string (possibly with : separating bytes) to output directly, however, this is strongly discouraged. Possible values are: "keyid" (Copy the Subject Key Identifier from the issuer's certificate) Often python programmers had to parse openssl output. This specifies the extension to indicate what types of applications is the public key The character encoding of explicitText can be specified by prefixing the value with UTF8, BMP, or VISIBLE followed by colon.
