计算字符串的哈希值

示例代码：

import hashlib
data = "Hello, world!"
hash_value = hashlib.sha256(data.encode()).hexdigest()
print("SHA-256哈希值:", hash_value)

计算文件的哈希值

示例代码：

import hashlib
def calculate_hash(file_path):
    with open(file_path, "rb") as file:
        content = file.read()
        hash_value = hashlib.md5(content).hexdigest()
        return hash_value
file_path = "path/to/file.txt"
hash_value = calculate_hash(file_path)
print("文件MD5哈希值:", hash_value)

使用HMAC进行消息认证

示例代码：

import hmac
import hashlib
key = b"secret_key"
message = "Hello, world!"
hmac_value = hmac.new(key, message.encode(), hashlib.sha256).hexdigest()
print("HMAC值:", hmac_value)

验证HMAC值

示例代码：

import hmac
import hashlib
key = b"secret_key"
message = "Hello, world!"
hmac_value = "..."
computed_hmac = hmac.new(key, message.encode(), hashlib.sha256).hexdigest()
if hmac.compare_digest(hmac_value, computed_hmac):
    print("HMAC值有效")
else:
    print("HMAC值无效")

加盐哈希存储密码

示例代码：

import hashlib
import os
def hash_password(password):
    salt = os.urandom(16)
    hash_value = hashlib.pbkdf2_hmac("sha256", password.encode(), salt, 100000)
    return salt + hash_value
def verify_password(password, stored_hash):
    salt = stored_hash[:16]
    stored_hash = stored_hash[16:]
    hash_value = hashlib.pbkdf2_hmac("sha256", password.encode(), salt, 100000)
    return hmac.compare_digest(stored_hash, hash_value)
password = "my_password"
stored_hash = hash_password(password)
# 验证密码
if verify_password(password, stored_hash):
    print("密码验证通过")
else:
    print("密码验证失败")

使用哈希值进行数据校验

示例代码：

import hashlib
def generate_checksum(data):
    checksum = hashlib.md5(data).hexdigest()
    return checksum
def verify_checksum(data, checksum):
    computed_checksum = hashlib.md5(data).hexdigest()
    if computed_checksum == checksum:
        return True
    else:
        return False
data = "Hello, world!"
checksum = generate_checksum(data)
print("校验和:", checksum)
# 验证校验和
if verify_checksum(data, checksum):
    print("校验和有效")
else:
    print("校验和无效")

加密敏感信息

示例代码：

import hashlib
def encrypt_data(data):
    encrypted_data = hashlib.sha256(data.encode()).hexdigest()
    return encrypted_data
sensitive_data = "sensitive_info"
encrypted_data = encrypt_data(sensitive_data)
print("加密后的敏感信息:", encrypted_data)

比较敏感信息的哈希值

示例代码：

import hashlib
def compare_hash(data1, data2):
    hash1 = hashlib.sha256(data1.encode()).hexdigest()
    hash2 = hashlib.sha256(data2.encode()).hexdigest()
    if hash1 == hash2:
        return True
    else:
        return False
data1 = "sensitive_info"
data2 = "sensitive_info"
if compare_hash(data1, data2):
    print("敏感信息一致")
else:
    print("敏感信息不一致")

生成随机的安全令牌

示例代码：

import hashlib
import secrets
def generate_token():
    token = secrets.token_hex(16)
    return token
security_token = generate_token()
print("安全令牌:", security_token)

验证数据的完整性

示例代码：

import hashlib
def generate_hash(data):
    hash_value = hashlib.md5(data.encode()).hexdigest()
    return hash_value
def verify_integrity(data, hash_value):
    computed_hash = generate_hash(data)
    if computed_hash == hash_value:
        return True
    else:
        return False
data = "Hello, world!"
hash_value = generate_hash(data)
# 验证数据完整性
if verify_integrity(data, hash_value):
    print("数据完整性验证通过")
else:
    print("数据完整性验证失败")

通过hashlib和hmac模块，我们可以轻松地实现数据的加密、哈希计算、消息认证等功能，确保接口自动化工作中的数据安全。以上示例代码展示了在实际接口自动化工作中常见的应用场景。
