AES — PyCryptodome 3.15.0 documentation - Read the Docs
AES¶ AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST. It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long. AES is very fast and secure, and it is the de facto standard for symmetric encryption. As an example, encryption can be done as follows:
ECC Encryption / Decryption - Practical Cryptography for …
Once we have the secret key, we can use it for symmetric data encryption, using a symmetric encryption scheme like AES-GCM or ChaCha20-Poly1305. Let's implement a fully-functional asymmetric ECC encryption and decryption hybrid scheme. It will be based on the brainpoolP256r1 curve and the AES-256-GCM authenticated symmetric cipher.

Cryptographic hash function - Wikipedia
A cryptographic hash function (CHF) is a mathematical algorithm that maps data of an arbitrary size (often called the "message") to a bit array of a fixed size (the "hash value", "hash", or "message digest").It is a one-way function, that is, a function for which it is practically infeasible to invert or reverse the computation. Ideally, the only way to find a message that produces a given ...
