About Encryption Algorithms
Encryption transforms your data into an unreadable format that can only be decrypted with the correct key. Different algorithms offer various trade-offs between security, speed, and compatibility.
AES-GCM
Advanced Encryption Standard with Galois/Counter Mode. Provides both confidentiality and authenticity. Recommended for most use cases.
Security:Very High
Performance:Fast
AES-CBC
AES with Cipher Block Chaining. Widely used method that requires padding. Good for encrypting larger amounts of data.
Security:High
Performance:Medium
AES-CTR
AES in Counter Mode. Turns block cipher into stream cipher. Fast and parallelizable.
Security:High
Performance:Very Fast
Important Security Notes:
- Always use strong, unique keys for sensitive data
- AES-GCM is recommended for most modern applications
- Key size directly affects security strength - 256-bit keys provide the highest security
- Remember to securely store your encryption keys
- Browser-based encryption is convenient but not suitable for highly sensitive data
