Encryption-decryption is one of those techniques which are quite popular. But, the complexity which is involved in this technique doesn’t allow its users to apply it in a simpler way.

Honey Encryption is an encryption tool in the works that fools an attacker with bogus decrypted data that looks like it could be a plausible guess at an encryption key or password.

MS researchers claim to crack encrypted database with old simple trick CryptDB developer says researchers were using database in way no one else would.

Of course the basic point about end-to-end encryption is that the operator does not hold the encryption keys, so cannot decrypt data itself.
