Legacy NSS security modules database


secmod.db is an NSS security modules database.

The security modules database is used to keep track of the NSS security modules. The NSS security modules export their services via the PKCS #11 API which NSS uses as its Services Provider Interface.

The command line utility modutil is used for managing PKCS #11 module information both within secmod.db files and within hardware tokens.

For new applications the recommended way of tracking security modules is via the pkcs11.txt configuration file used in conjunction the new sqlite-based shared database format for certificate and key databases.
