Encryption Tools
Securely encrypt and decrypt text using industry-standard algorithms. All processing happens in your browser for maximum security.
Advanced Encryption Standard (recommended)
Understanding Encryption
Encryption is the process of converting readable data (plaintext) into an encoded format (ciphertext) that can only be decrypted by authorized parties. Key concepts include:
- Symmetric Encryption: Uses the same key for encryption and decryption (e.g., AES)
- Asymmetric Encryption: Uses different keys for encryption and decryption (e.g., RSA)
- Encryption Key: Secret value required to decrypt the data
- Initialization Vector (IV): Random value used to ensure unique encryptions
Supported Algorithms
AES (Advanced Encryption Standard)
Industry standard symmetric encryption. Supports 128, 192, and 256-bit keys.
DES (Data Encryption Standard)
Legacy algorithm with 56-bit key. Not recommended for sensitive data.
Triple DES
Applies DES three times. More secure than standard DES but slower than AES.
RC4
Stream cipher. Fast but vulnerable to certain attacks. Use with caution.
Security Best Practices
Key Management
Use strong, random encryption keys and store them securely. Never share keys through insecure channels.
Algorithm Selection
Use AES-256 for most applications. Avoid deprecated algorithms like DES for sensitive data.
Data Protection
Encrypt sensitive data both in transit and at rest. Use secure key exchange methods.
Quick Tips
- • Use AES-256 for sensitive data
- • Keep encryption keys secure
- • Use unique keys for each use
- • Backup encrypted data safely
- • Verify decrypted data integrity
- • Use strong, random passwords
