# CiphersOnline
> Educational and utility website for classical ciphers, encoding, decoding, and text transformation tools.
CiphersOnline provides browser and API-assisted tools for learning, testing, encrypting, decrypting, encoding, and decoding text. Classical ciphers on this site are for education, experiments, and historical understanding, not for protecting sensitive information.
Primary language for this file: English.
Available website locales: en, ru, de, es, fr, it, pt, tr
## Core Pages
- [Home](https://ciphersonline.com/): Main entry point for cipher and encoding tools.
- [Glossary](https://ciphersonline.com/glossary): Definitions of cryptography, cipher, encoding and hashing terms.
- [Guides](https://ciphersonline.com/guides): Long-form tutorials, deep dives and history on ciphers and codes.
- [HTML Sitemap](https://ciphersonline.com/sitemap): Human-readable list of published categories and tools.
- [XML Sitemap](https://ciphersonline.com/sitemap.xml): Complete crawl map with locale alternates.
- [Contact](https://ciphersonline.com/contacts): Contact page for site feedback and support requests.
## Tool Categories
- [Classical Ciphers](https://ciphersonline.com/classical-ciphers): Explore historical encryption methods including Caesar, Vigenere, Playfair, Beaufort, Vernam, Atbash, Gronsfeld, Rail Fence, Columnar Transposition, ROT13, Hill, Affine, and other classical ciphers. Encrypt, decrypt, and learn how traditional cryptography works online.
- [Cipher Solver](https://ciphersonline.com/cipher-solver): Paste unknown ciphertext into a cipher identifier, cipher decoder, and cipher solver in one place. The tool detects likely cipher or encoding types, runs supported solvers automatically, and shows the most likely plaintext first with ranked alternative decryptions and evidence.
- [Encoding and Data Conversion](https://ciphersonline.com/encoding): Tools for encoding, decoding, and converting text and binary data. Use Base64, Hex, URL Encode, Binary, ASCII, Unicode, JWT, and other formats online.
- [Codes & Alphabets](https://ciphersonline.com/codes-and-alphabets): Explore communication codes, symbolic alphabets, character substitution systems, and alternative text representations. Convert text using Morse code, A1Z26, Polybius Square, Bacon cipher, and other historical coding systems used for communication, education, puzzles, and secret messages.
- [Text Analysis & Cryptanalysis](https://ciphersonline.com/text-analysis): Analyze text with frequency analysis, language statistics, and classical cryptanalysis tools. Study letter distributions, repeated patterns, n-grams, coincidence, entropy, and clues that help identify or break historical ciphers.
- [Hashing & Password Security](https://ciphersonline.com/hashing): Generate hashes online with SHA-256, SHA-512, SHA-3, SHA-1, and MD5; create keyed HMAC values; and derive or verify password hashes with Argon2, bcrypt, and PBKDF2. All calculations run locally in your browser.

What verification unlocks
See how your site is discovered—and control what agents see.
- See your website in the map
Review your indexed topics, nearby publishers sharing headings, measured listing exposure and map snapshots in a private report for your website.
- Control what agents see
Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.
Let your coding agent verify it
If your coding agent is authorized to manage this website, paste these instructions into it.
Claim my listing on Agent Web Map for ciphersonline.com:
1. POST https://agentwebmap.com/v1/sites/ciphersonline.com/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://ciphersonline.com/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/ciphersonline.com/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/ciphersonline.com).
