Text Encryption

Security REST API MCP

Encrypt text with a password using AES-256-GCM (key derived with PBKDF2-SHA256, 100000 iterations) and return a base64 ciphertext, or decrypt such a ciphertext back to the original text. The base64 blob is salt(16) + iv(12) + ciphertext, compatible with the FindUtils Text Encryption page.

This page documents the MCP tool findutils:text_encryption. See the REST reference →
