What is timestamp validation details:

Timestamping, or Trusted Timestamping, is a standard to prove the existence of data at a specific time and to verify its integrity. RFC 3161 is an open and widespread implementation of this process.

By applying a certified timestamp the LibraCyber Email Archiver also certifies the integrity of the email. Any modification of the email content invalidates the signature and the certified timestamp provides legal proof of authenticity and integrity for each email.

Timestamps are automatically applied by the LibraCyber Email Archiver to every archived email. No configuration is needed, this is a feature that is provided out of the box by every LibraCyber Email Archiver appliance.

How is it implemented in the LibraCyber Email Archiver?

In the LibraCyber Email Archiver emails are stored as .eml files contained within a zip file. The .eml file guarantees that the email is stored without any modification, ensuring maximum compliance. The zip container provides compression and de-duplication without any data loss.

The use of widespread standards (.eml and .zip) for storing email guarantees that the archived email can be read and recovered at any time in the future even without our software. Moreover, the .eml files contain, through the use of extra headers added by the archiver, all the information needed to completely rebuild the email index.

The algorithm used by the LibraCyber Email Archiver is SHA256.
