This software enables communication with PKCS#11 cryptographic modules by providing essential functions.
This module's interface includes several global variables that enhance its usability. One such variable is $DefaultPinArg. It sets the default PKCS#11 pin arg on Net::NSS::SSL instances. This function is useful in scenarios where PKCS#11 pin arg on sockets cannot be directly controlled, especially when used with NSS and LWP.
Moreover, Crypt::NSS::PKCS11 has useful class methods. The set_password_hook() method, for instance, sets the function to invoke when a PKCS#11 module needs a password. The argument CALLBACK can either be a code reference or a fully qualified function name.
Another class method is find_cert_by_nickname(), which locates a certificate by nickname. Here, the $arg argument passes to the hook set by set_password_hook. Another class method, find_key_by_any_cert(), finds a private key for a certificate. Similarly, the $arg argument passes to the hook set by set_password_hook.
Overall, Crypt::NSS::PKCS11 is a reliable Perl module that simplifies communication between PKCS#11 cryptographic modules. Its functions and global variables enhance its usability, and class methods offer efficient solutions for specific tasks.
