Compact Encrypted Text
Opaque Base64 representation of the same encryption result.
Encrypt-Decrypt
Encrypt and decrypt text with a secret key
Use /secret for a strong key.
Encrypted JSON / Object
Structured metadata and ciphertext from the same operation.
Both cards are one encryption. Base64 is encoding, not encryption. The secret is never included.
Decrypted Text
Enter text and a secret, choose Encrypt or Decrypt, then run. Stays in your browser. Ctrl+Enter to run.
How to use this tool as an API
GET and POST. UI stays in the browser. Default v=2; v=1 is legacy. Returns data.compact and data.json. PBKDF2 iterations default 310,000 (max 310,000). GET query strings can be logged or cached — prefer POST for secrets.
GET, POST /api/encryption
Params: str, key, mode, v?, iter?
Example
GET /api/encryption?str=hello&key=your-secret&mode=encrypt
POST /api/encryption
Content-Type: application/json
{"str":"hello","key":"your-secret","mode":"encrypt"}
