aes

Overview ¶

Package aes provides encryption and decryption functions using the AES algorithm. It includes functions for generating AES keys, encrypting plaintext, and decrypting ciphertext.

The package uses AES-256 encryption in CBC mode with PKCS7 padding. Key generation pads or truncates the provided key to ensure it's always 32 bytes (256 bits).

Usage:

key := []byte("your-secret-key")
plaintext := "Hello, World!"

// Encrypt
encrypted, err := aes.Encrypt(plaintext, key)
if err != nil {
    // Handle error
}

// Decrypt
decrypted, err := aes.Decrypt(encrypted, key)
if err != nil {
    // Handle error
}

Note: Always use a secure method to generate and store your encryption keys. Never use hardcoded keys in production environments.
