3 MCP servers and agent skills in the Cryptography category, ranked by quality score.
Local byte-wrangling toolbox: encoding (hex/Base64/Base32/Base58/Base45…), cryptographic + CRC hashing, base conversion, and CSPRNG tokens/passphrases, plus an opt-in Ethereum/EVM toolset (keccak, ABI/RLP codecs, EIP-191/712 hashing, function/event selectors, EIP-55). No network calls. `uvx mcp-bytesmith`.
A Model Context Protocol server that brings the capabilities of [enigmapython](https://github.com/denismaggior8/enigma-python) library to LLMs, allowing them to encrypt and decrypt messages using historically accurate Enigma machine emulators.
