What is Encrypt / Decrypt Text?
The Encrypt / Decrypt tool lets you encrypt text using AES-256 encryption with a password, or encode and decode text using Base64. AES encryption is the same standard used by banks and governments. Use it to protect sensitive text before sharing it, or to decode Base64 strings you receive from APIs or emails.
How to Use
Choose between AES encryption or Base64 encoding.
Select whether you want to encrypt or decrypt.
Enter your text and password (for AES), then click the button to get the result.
Why Use This Tool?
Sometimes you need to send a password, API key, or private message through an insecure channel. This tool lets you encrypt it first so only the person with the password can read it. Everything runs in your browser - your text and password are never sent to any server.
FAQ
It uses AES-256 with PBKDF2 key derivation and a random salt. This is the same standard used in professional security applications.
No. AES-256 encryption cannot be broken without the correct password. Make sure you use a strong password and share it securely.
No. Base64 is encoding, not encryption. It converts text to a different format but anyone can decode it. Use AES if you need actual security.
