About
Ethereum Keystore Encryption is an MCP server that encrypts and decrypts Ethereum keystore JSON V3 files using scrypt or PBKDF2, the standard formats for protecting a private key with a passphrase. A solo builder reaches for it when adding secure cold-storage or wallet-import flows to a crypto app and wants keystore handling available to an agent.
