# Cryptography
* Often data is just encoded in base64 or hex. Other times it's just compressed (gzip):
- text 32 characters long --> md5 hash.
- 40 characters long --> SHA1 hash.
- equal signs spread --> base64 encoded string.
- text only letters, without numbers or special characters --> Caesar, Vigenere, or other type of cipher.
- hints about keys and signing --> likely RSA.
