I.A.I.
I.A.I. is a way to see important details about the encrypted files. This acronym means "Integrity, Authenticity and Irretractability" (non-repudiation).
In a simple way, you can inspect encrypted files and see if they are 100% integral, came from a legitimate person (author), who had last edited them, and all the people authorized to open them.
Notice: this function is restricted to files encrypted by Digital Certificates.
