What is Text Encryption?
Text encryption is the process of converting plain, readable text into an unreadable format (ciphertext) using cryptographic algorithms and a secret key. Only those with the correct key can decrypt and read the original message, making it essential for protecting sensitive information.
- Confidentiality: Keeps sensitive data private and secure
- Two-Way: Unlike hashing, encryption can be reversed with the key
- Key-Based: Requires a password or key for encryption/decryption
- Multiple Algorithms: Different encryption methods for various security needs
- Private: Encryption happens locally in your browser
Common Uses
- Secure Messaging: Protect private communications from eavesdropping
- Password Protection: Encrypt passwords before storing them
- Data Storage: Secure sensitive information in databases
- API Tokens: Protect authentication credentials
- Personal Notes: Keep private notes and journal entries secure
How to Use
- Select Encrypt or Decrypt mode
- Choose an encryption algorithm (AES is recommended)
- Enter a strong secret key (longer is better)
- Paste or type your text in the input field
- Click the process button to encrypt or decrypt
- Use the Swap button to quickly reverse the operation
Glossary
- AES
- Advanced Encryption Standard - the most widely used modern encryption algorithm, considered highly secure.
- DES
- Data Encryption Standard - an older algorithm now considered insecure due to small key size.
- TripleDES
- Applies DES encryption three times to increase security, but slower than modern algorithms.
- Ciphertext
- The encrypted, unreadable output of an encryption algorithm.
- Plaintext
- The original, readable text before encryption or after decryption.
- Encryption Key
- A secret password or value used to encrypt and decrypt data.
- Symmetric Encryption
- Encryption method where the same key is used for both encryption and decryption.
- Block Cipher
- Encryption method that processes data in fixed-size blocks (e.g., 128 bits).
