MULTI-LAYER ENCRYPTION – DEFINITION
Multi-layer encryption is the process of encrypting an already encrypted file, one or several times more. This can be done either by using the same algorithm multiple times, or by using different algorithms.
Is multi-layer encryption more secure?
The purpose of using multi-layer encryption is to make an encrypted file transfer – that in theory already should be secure – even more secure. Encrypting something that has already been encrypted gives increased security.
If you are not using multi-layer encryption, your information is not as safe as it could be.
