How do you choose a cipher?
If there are only 2 different symbols, it is likely the cipher is Baconian. If there are 5 or 6 it is probably a polybius square cipher of some sort, or it may be ADFGX or ADFGVX. If there are more than 26 characters it is likely to be a code or nomenclator of some sort or a homophonic substitution cipher.
Which encryption mode is most secure?
AES encryption
Originally adopted by the federal government, AES encryption has become the industry standard for data security. AES comes in 128-bit, 192-bit, and 256-bit implementations, with AES 256 being the most secure. In this article, we’ll explain how AES 256 encryption works and how it can be used to protect your data.

What are the qualities of a good block cipher?
Ciphers are incredibly complex, to the point most people probably don’t appreciate them, myself included. Trying to make one from scratch might help with this, so I’m looking for a list of qualities/achievables that can be worked towards for years to come. This is the list so far, for a good block cipher at different learning levels:
Which is more secure stream cipher or block cipher?
It is usually more complex and secure, but slower. Examples of block cipher include the DES, RC5, and Blowfish. Stream Cipher: A stream cipher, on the other hand, encrypts one byte of data at a time. Unlike block cipher, each bit in this mode is encrypted with a different key.
What do I need to know about cryptography algorithms?
It can be a reliable encryption option as long as the key lengths are over 128 bits. The more advanced 128-bit Twofish is capable of using key lengths up to 256 bits. In terms of security, its security strength is almost equal to that of the AES. What Do I Need to Know About Cipher Modes?
