    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
