Questionnaire

Does password-based encryption require asymmetric encryption algorithms?

True
False

One of the most used secure password to key derivation algorithms is called:

Key from Password Derivation Function (KPDF)
Password-based Key Derivation Function (PBKDF)
Password to Key Derivation Function (PKDF)

Which of these are common hash functions?

Sunshine
MD5
SHA1
Whirlpool

Which elements of a secure hashing scheme mitigate brute-force attacks on password hashes?

Iterations
Complex passwords
Salt
Secure hash function

What is the best way to create a secure hashing scheme for your application?

Simply using a secure and long hash function
Concatenating a password with a salt and using a secure and long hash function
Using a specifically-designed hashing scheme developed by cryptographers

ZIP-based AES encryption is broken.

True
False

Which crypto schemes are supported by CrococryptFile?

Password-based AES encryption
Windows Keystore based RSA/AES encryption
OpenPGP Keyfile based AES encryption

Which AES key length in bits is used by CrococryptFile by default?

What does CrococryptFile's headerless encryption mean?

No file headers and no file extension is used, hence the encrypted file looks like a file full of random binary data.
Since no plain data can be written to the file for this mode, only password-based encryption can be used.
Since no static parameters are written to the file, some parameters for the PBE have to be determined by trial and error.
