创建密钥
如下代码可以创建MasterKey,返回MasterKeyId,创建时间等等。
kmsClient.create_masterKey("test", protectedby_class.HSM,
keyspec_class.AES_256,
origin_class.EXTERNAL,360)
列举MasterKey
result = kmsClient.list_masterKey(10)
#打印所有密钥keyid
for index in range(len(result.keys)):
print result.keys[index].key_id
加密数据
keyId = "xxxxxxx"
plaintext = base64.b64encode("hellobaby")
result = kmsClient.encrypt(keyId, plaintext)
print result.ciphertext
解密数据
keyId = "xxxxxx"
ciphertext = "xxxxxxxxxxxxx"
result = kmsClient.decrypt(keyId, ciphertext)
print result.plaintext
生成DataKey
keyId = "xxxxxx"
kmsClient.generate_dataKey(keyId, keyspec_class.AES_128, 128)
使MasterKey处于可用状态
keyId = "001f9ef4-0a4b-1333-db42-e79dbd80fd25"
kmsClient.enable_masterKey(keyId)
使MasterKey处于不可用状态
keyId = "001f9ef4-0a4b-1333-db42-e79dbd80fd25"
kmsClient.disable_masterKey(keyId)
删除MasterKey
keyId = "001f9ef4-0a4b-1333-db42-e79dbd80fd25"
kmsClient.scheduleDelete_masterKey(keyId, 7)
取消删除MasterKey
keyId = "001f9ef4-0a4b-1333-db42-e79dbd80fd25"
kmsClient.cancelDelete_maaterKey(keyId)
获取MasterKey详细信息
keyId = '001f9ef4-0a4b-1333-db42-e79dbd80fd25'
result = self.client.describe_masterKey(keyId)
print result.key_metadata.protected_by
获取导入密钥参数
keyId = "16f97e43-3bdc-c97d-903f-4d7f2bc5828e"
publicKeyEncoding = publickeyencoding_class.PEM
result = self.client.get_parameters_for_import(keyId, publicKeyEncoding)
print result.public_key
