comment What is the difference between SHA-3(Keccak) and previous generation SHA algorithms?
Not to mention that MD5 (which was clearly broken) was also based on the Merkle-Damgård scheme). So, they were real suspicions that flaws would be found soon.

comment Can blockchain be used in a comparable way to an encrypted SQLite database?
@Bendy: Blockchain can be used to certify transactions between two or several participants in a distributed manner. But, it cannot achieve any encryption scheme. You should try to explain a bit more what you meant...

comment OTP - Reusing key IS SECURE! PROVED!
@Alvin : Then, the keys are used only once and, there we go, you re-discovered OTP once again ! Congrats ! :-)

comment Is cryptanalysis of CTB-Locker really impossible?
I didn't mean "breaking ECC" or "breaking AES", I was more thinking about an error in the way the things have been arranged to build the whole encryption scheme or specificities that are linked to the very peculiar way the encryption is used here. For example, if you have a partial back-up of your file, you will have access to a reasonable quantity of cleartext/ciphertext couple that you may use. Or, is there a flaw in the entropy of the chosen keys... But, of course, I believe in the security of ECC and AES... I am not that naive !
