Summary

The IMA (Integrity Measurement Architecture) is a key component of the

Linux integrity subsystem designed to ensure integrity, authenticity,

and confidentiality of systems including hardware root of trusts (TPM).

This tool allows signing of files in userspace, inclusding options of

including the signature in xattr or a .sig file, using signing keys

stored in the kernel keyring to ensure they're not recoverable.
