💡 For developers: AES encryption with OpenSSL

openssl enc -aes-256-cbc -salt -in file.txt -out file.enc -k "your_password"

# Encrypt a file using AES-256-CBC

openssl enc -d -aes-256-cbc -in file.enc -out file_decrypted.txt -k "your_password"

# Decrypt a file using AES-256-CBC

About AES Encryption

The Advanced Encryption Standard (AES) is a symmetric encryption algorithm established by the U.S. National Institute of Standards and Technology (NIST) in 2001. It is widely used across the globe for securing sensitive data.

AES Key Characteristics

• Symmetric algorithm: Uses the same key for encryption and decryption
• Block cipher: Encrypts data in fixed-size blocks (128 bits)
• Key sizes: 128, 192, or 256 bits (10, 12, or 14 rounds respectively)
• Considered highly secure and is the standard for many government and financial institutions

🔒 Security Note: AES is considered extremely secure when implemented correctly with appropriate key sizes. For most applications, AES-256 provides a very high level of security.

Common Uses of AES

AES encryption is used in a wide variety of applications to protect sensitive data:

Application	Usage
Wi-Fi Security	WPA2 and WPA3 protocols use AES for securing wireless networks
File Encryption	Tools like VeraCrypt and BitLocker use AES for full disk encryption
SSL/TLS	Secure web connections often use AES to encrypt data in transit
Messaging Apps	Applications like WhatsApp and Signal use AES for end-to-end encryption

AES vs Other Encryption Algorithms

Algorithm	Key Size	Security Status	Common Uses
AES	128-256 bits	Highly Secure	Government, finance, secure communications
RSA	2048-4096 bits	Secure	SSL certificates, digital signatures
DES	56 bits	Broken	Legacy systems (no longer recommended)
3DES	112-168 bits	Deprecated	Legacy systems (being phased out)

⚠️ Important: Always use strong, randomly generated keys for AES encryption. Weak keys can compromise the security of your encrypted data. For maximum security, use AES-256 with a strong mode like GCM.
