What is Encryption
Converting data into unreadable format for protection
Encryption is the process of converting data into an unreadable format using cryptographic algorithms to protect information from unauthorized access.
Types of Encryption
- Symmetric — one key for encryption and decryption (AES, DES)
- Asymmetric — public/private key pair (RSA, ECC)
- Hashing — one-way function for passwords (SHA-256, bcrypt)
- Hybrid — combination of both methods
Business Applications
- Protecting customer personal data
- Database encryption
- Secure password storage
- File and document protection
Encryption Standards
- AES-256 — banking standard
- TLS 1.3 — web traffic protection
- PGP — email encryption
- FIPS 140-2 — US government standard
