aes、rsa、ecc、des、3des、rabin、elgamal、diffie-hellman加密代码

AES（高级加密标准）加密代码：

from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes

key = get_random_bytes(16)
cipher = AES.new(key, AES.MODE_EAX)
ciphertext, tag = cipher.encrypt_and_digest(data)

RSA（Rivest-Shamir-Adleman）加密代码：

from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_OAEP

key = RSA.generate(2048)
cipher = PKCS1_OAEP.new(key)
ciphertext = cipher.encrypt(data)

ECC（椭圆曲线加密）加密代码：

from tinyec import registry

curve = registry.get_curve('secp256r1')
public_key = curve.g * private_key
shared_key = public_key * remote_private_key

DES（数据加密标准）加密代码：

from Crypto.Cipher import DES

key = b'abcdefgh'
cipher = DES.new(key, DES.MODE_ECB)
ciphertext = cipher.encrypt(data)

3DES（Triple DES）加密代码：

from Crypto.Cipher import DES3

key = b'abcdefghabcdefghabcdefgh'
cipher = DES3.new(key, DES3.MODE_ECB)
ciphertext = cipher.encrypt(data)

Rabin加密代码：

from Crypto.PublicKey import Rabin
from Crypto.Cipher import PKCS1_v1_5

key = Rabin.generate(2048)
cipher = PKCS1_v1_5.new(key)
ciphertext = cipher.encrypt(data)

ElGamal加密代码：

from Crypto.PublicKey import ElGamal
from Crypto.Cipher import ElGamal
from Crypto import Random

key = ElGamal.generate(2048, Random.new().read)
cipher = ElGamal.new(key)
ciphertext = cipher.encrypt(data, 0)

Diffie-Hellman加密代码：

from Crypto.PublicKey import DH
from Crypto.Hash import SHA256

key = DH.generate(2048)
public_key = key.publickey()

以上代码仅用于演示目的，实际使用时应该仔细考虑安全性和性能等因素。
