Python 通过DeDecodeError进行RSA加密
我正在构建一个简单的flask应用程序,允许用户发布数据,并返回一个经过RSA公钥加密和base64编码的字符串 Flask应用程序路径如下所示Python 通过DeDecodeError进行RSA加密,python,encryption,flask,Python,Encryption,Flask,我正在构建一个简单的flask应用程序,允许用户发布数据,并返回一个经过RSA公钥加密和base64编码的字符串 Flask应用程序路径如下所示 def index(eyaml_output=""): if request.method == 'GET': return render_template('index.html.j2', eyaml_output=eyaml_output) elif request.method == 'POST': input = request
def index(eyaml_output=""):
if request.method == 'GET':
return render_template('index.html.j2', eyaml_output=eyaml_output)
elif request.method == 'POST':
input = request.form['eyaml_input']
output = helpers.encrypt(input)
eyaml_output = output
from Crypto.Cipher import PKCS1_OAEP
from Crypto.PublicKey import RSA

def encrypt(arg):
with open('eyaml_public.key') as public_key_file:
public_key = public_key_file.read()
pubkey = RSA.importKey(public_key)
cipher = PKCS1_OAEP.new(pubkey)
output = base64.b64encode(cipher.encrypt(arg))
return output
encrypt函数如下所示
def index(eyaml_output=""):
if request.method == 'GET':
return render_template('index.html.j2', eyaml_output=eyaml_output)
elif request.method == 'POST':
input = request.form['eyaml_input']
output = helpers.encrypt(input)
eyaml_output = output

with open('eyaml_public.key') as public_key_file:
public_key = public_key_file.read()
pubkey = RSA.importKey(public_key)
cipher = PKCS1_OAEP.new(pubkey)
output = base64.b64encode(cipher.encrypt(arg))
return output
这一切都可以在命令行中正常工作。但是当在flask中调用时,我得到以下UnicodeDecodeError
UnicodeDecodeError: 'ascii' codec can't decode byte 0xda in position 0: ordinal not in range(128)
我尝试过切换到utf-8,但也遇到了类似的错误
编辑:
我正在使用Python2.7VirtualEnv活动版进行测试。输出本身似乎也不重要。即使在执行中间步骤时,也会出现相同的Unicode错误。问题似乎发生在加密部分,而不是base64编码。下面是完整的堆栈跟踪

如果您在
arg
参数上添加对的调用,它应该可以工作。encrypt
方法需要一个字节序列,但得到的却是一个str

您可能在控制台中使用了不同版本的Python-3.x和Flask,2.x,因为后者的base64.b64encode
生成了一个字符串而不是字节,所以您不必解码任何内容。为了安全起见,请始终对base64输出进行解码,例如,返回输出。decode(“拉丁语-1”)
