Secure your text with various encryption algorithms
Want to embed this encryption tool on your website? Use this code:
Simple letter substitution cipher with a fixed shift:
How it works: Each letter is shifted 3 positions forward in the alphabet.
More secure polyalphabetic substitution cipher:
How it works: Uses a keyword to determine multiple Caesar shifts.
Encoding scheme for binary-to-text conversion:
Note: Base64 is encoding, not encryption, but often used for obfuscation.
Simple symmetric key encryption:
How it works: Applies XOR operation between text and key bytes.
Encrypt private messages before sharing them through potentially insecure channels.
Encrypt sensitive information like passwords before storing them in databases.
Encrypt text content before saving to files for additional security.
Use encryption for secure communication between applications or services.

Not just a tool - includes comprehensive guides, examples, and best practices for encryption.
Text encryption is the process of converting plain text into ciphertext using an algorithm and a key, making it unreadable to anyone without the proper decryption key. This ensures that only authorized parties can access the original information.
Symmetric encryption uses the same key for encryption and decryption, while asymmetric uses different keys.
The security of encryption depends heavily on key length and randomness. Longer keys are generally more secure.
Different algorithms have different performance characteristics. Some are faster but less secure, others are slower but more secure.
Proper key generation, storage, distribution, and rotation are critical for maintaining encryption security.
