Create a decrypted mapping of an encrypted volume. Note: Enabling TRIM may leak minimal information (freed blocks, possibly revealing the filesystem in use), but is still recommended since the data stays safe and SSDs without TRIM wear out faster.

Open a LUKS volume and create a decrypted mapping at /dev/mapper/mapping_name

cryptsetup open /dev/sdXY mapping_nameIdentify

Use a keyfile instead of a passphrase

cryptsetup open --key-file path/to/file /dev/sdXY mapping_nameIdentify

Allow the use of TRIM on the device

cryptsetup open --allow-discards /dev/sdXY mapping_nameIdentify

Write the --allow-discards option into the LUKS header (the option will then always be used when you open the device)

cryptsetup open --allow-discards --persistent /dev/sdXY mapping_nameIdentify

Open a LUKS volume and make the decrypted mapping read-only

cryptsetup open --readonly /dev/sdXY mapping_nameIdentify
