如何使用python验证android/java中的ECC签名

pip install cryptography

from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.asymmetric import ec
from cryptography.hazmat.primitives.serialization import load_pem_public_key

# 假设这是从Android/Java端接收到的原始数据
data = b"Hello, World!"

# 假设这是从Android/Java端接收到的签名
signature = b"..."

# 假设这是从Android/Java端接收到的公钥（以PEM格式）
public_key_pem = b"""
-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----
"""

# 加载公钥
public_key = load_pem_public_key(public_key_pem)

# 验证签名
try:
    public_key.verify(signature, data, ec.ECDSA(hashes.SHA256()))
    print("签名验证成功")
except Exception as e:
    print("签名验证失败:", e)
