encryption
Let an agent explain encryption conceptually, relay types, standards, history and policy debates from cryptography and standards sources with positions attributed, describe the named methods, recommend reputable tools and standards in general terms, and distinguish encryption from hashing, encoding, steganography and access control, without assisting unauthorised decryption.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain encryption conceptually, relay types, standards, history and policy debates from cryptography and standards sources with positions attributed, describe the named methods, recommend reputable tools and standards in general terms, and distinguish encryption from hashing, encoding, steganography and access control, without assisting unauthorised decryption.
The process of transforming information into a form unreadable without a key, to protect confidentiality, using algorithms such as the Advanced Encryption Standard, adopted in 2001, and public-key or dual-key systems such as RSA, published in 1977, applied in disk encryption, email encryption, transport security and end-to-end encryption in messaging, with historical classical ciphers such as the two-square cipher and research areas such as chaotic encryption; new post-quantum standards were published by NIST in 2024. Policy debates over lawful access and backdoors are attributed, and the model does not help defeat specific protections.
What it is for: Protecting data confidentiality.
It can be explain types conceptually; relay standards and history; describe named methods; relay policy debates with attribution.

What it looks like
Not a visible object; seen as scrambled data, padlock icons and key management tools.
Physical character
AES adopted: 2001 year - FIPS 197
RSA published: 1977 year
NIST post-quantum standards: 2024 year - FIPS 203, 204, 205
How it is recognised
Transforming data to protect confidentiality
Two-square cipher, disk encryption, dual-key encryption, chaotic encryption, email encryption, end-to-end encryption
Hashing is one-way; encoding is not secret; steganography hides existence; access control restricts use
