How AES-256 Encryption Works
AES (Advanced Encryption Standard) is a symmetric encryption algorithm that uses a 256-bit key. This means there are 2^256 possible keys - more than the number of atoms in the observable universe.
Common Use Cases
File encryption is essential for protecting sensitive data in various scenarios:
Personal Privacy
Protect personal photos, documents, and sensitive files from unauthorized access.
Business Security
Secure confidential business documents, financial records, and client data.
Cloud Storage
Encrypt files before uploading to cloud services for added security.
Secure Sharing
Share sensitive files via email or messaging apps with password protection.
