Variables

var (
	CBC cbc // CBC (Cipher Block Chaining): Encrypts each block of plaintext with XOR chaining to the previous ciphertext block.
	CFB cfb // CFB (Cipher Feedback): Encrypts an IV and XORs it with plaintext segments, turning AES into a self-synchronizing stream cipher.
	CTR ctr // CTR (Counter): Encrypts a counter value and XORs it with plaintext, effectively turning AES into a stream cipher.
	ECB ecb // ECB (Electronic Codebook): Encrypts each block of plaintext independently.
	GCM gcm // GCM (Galois/Counter Mode): Combines CTR mode encryption with Galois mode for authentication, providing confidentiality and integrity.
	OFB ofb // OFB (Output Feedback): Encrypts an IV to create a keystream, XORed with plaintext to produce ciphertext, making AES a stream cipher.
