Encrypt text with Triple DES instantly using a passphrase-based browser tool.
Use this 3DES Encrypt tool to encrypt plain text with Triple DES and return a Base64 ciphertext. It is useful for legacy compatibility testing, reversible crypto demos, browser-side experiments, and understanding how passphrase-based encryption transforms readable text into encrypted output.

Input
secret123 hello world
Output
Base64 encrypted text
The first line is the passphrase and the lines below are the plaintext.
Input
demo-key
{"name":"John","role":"admin"} Output
Base64 encrypted text
Useful for testing how structured text looks after 3DES encryption.
Fix: Put the passphrase on the first line and the plaintext below it.
Fix: You must use the exact same passphrase to decrypt the ciphertext.
Fix: 3DES is mainly useful for legacy compatibility, not new secure system design.
Fix: Always put the passphrase first and the plaintext below it.
Fix: This tool returns Base64 ciphertext for easier copy and reuse.
It encrypts plain text with Triple DES and returns a Base64 ciphertext.
Put the passphrase on the first line and the plaintext below it.
It is mostly useful for legacy compatibility and testing rather than new system design.
It returns Base64 ciphertext.
The reverse tool is 3DES Decrypt.
