ecryptfs-insert-wrapped-passphrase-into-keyring [options]

--fnek
    Indicates that the passphrase being inserted is an FNEK (File Name Encryption Key) passphrase.

--noask
    Suppresses prompting the user for confirmation before inserting the passphrase.


    The mount point of the eCryptfs encrypted directory. This is a required argument.

The `ecryptfs-insert-wrapped-passphrase-into-keyring` command is a utility designed to securely add a wrapped passphrase associated with an eCryptfs mount point into the user's keyring. This allows the system to automatically unlock the encrypted directory when the user logs in, without requiring them to manually enter the passphrase. This command is typically used in conjunction with other eCryptfs tools to automate the mounting process and provide a seamless user experience.

The command internally uses the `keyctl` utility to manage the user's keyring. It decodes the wrapped passphrase and inserts it into the keyring under a specific description related to the eCryptfs mount point. It is crucial that the process invoking this command has the necessary permissions to access the eCryptfs metadata and the user's keyring.

This command must be run as the user who owns the eCryptfs encrypted directory or with sufficient privileges. Incorrect usage can lead to data access issues. Ensure the ecryptfs module is properly loaded before use.

It's critical to ensure the wrapped passphrase is stored securely and only accessible to authorized users. Avoid storing wrapped passphrases in easily accessible locations or sharing them with untrusted parties. Regularly review and update your security practices to protect your encrypted data.

If the command fails, check the following:
- Ensure the eCryptfs module is loaded.
- Verify the user has sufficient permissions.
- Check for errors in the mount point path.
- Examine the system logs for relevant error messages.

The `ecryptfs-insert-wrapped-passphrase-into-keyring` command was developed as part of the eCryptfs project to simplify the process of automatically mounting encrypted directories. It streamlines the interaction with the kernel keyring service, eliminating the need for users to manually manage passphrases during the login process. It's been an integral part of the eCryptfs toolset and provides a secure and convenient method for managing encrypted files.
