Manages X.509 SSL/TLS certificates. It uses the Common Data Security Architecture (CDSA) in much the same way that /System/Library/OpenSSL/misc/CA.pl uses OpenSSL to ease the process of managing certificates.

As arguments, it takes a single-letter command, often followed by a filename, and possibly some options.

Options

a

When adding an item to a keychain, create a key pair including a private key with a more restrictive ACL than usual. (The default behavior creates a private key with no additional access restrictions, while specifying this option adds a confirmation requirement to access the private key that only certtool is allowed to bypass.)

As a command, walks you through a series of interactive prompts to create a certificate and a public/private key pair to sign and possibly encrypt it. The resulting certificate (in DER format) is stored in your default keychain.

Tip

As an option, instructs certtool to create a new keychain by the name given in the ...
