我使用此代码创建公钥和私钥:
import rsa
(pubkey, privkey) = rsa.newkeys(512)
然后将其转换为PEM格式:
exppub =pubkey.save_pkcs1(format='PEM')
exppriv = privkey.save_pkcs1(format='PEM')
当我使用此键加密按摩时:
message = 'hello Bob!'
crypto = rsa.encrypt(message, pubkey)
获得的加密消息如下:
"@\xc4\xb2\x14r\xf1x\xb8\xb2\t;\x9a:\x1dl\x11\xe2\x10\xa9E\xee\x8b\xac\xd0\xd3Y\xfb}\xd9@\xdd\x0c\xa5\xd2\xfc1\xd6\x06\xf0\xb8\x944\xe1\xc2r\xe5anyq\xac\xdfh\xeb\x10\x80\x98\xa1\xee'\xe6hpi"
我知道它应该是这样的:
SEcPB1mYNrfeE4zP4RI3z2K4Rh9HDNfPhuF28IyxHFjEOJ9Z+1zdIwPF0jsJGQDJyKpAju7dcYueHHXXeH8d+w==
如何更改此格式?
答案 0 :(得分:2)
您可能会注意到加密消息每次生成时都会更改:
>>> import rsa
>>>
>>> (pubkey, privkey) = rsa.newkeys(512)
>>> message = 'hello Bob!'
>>> for _ in range(5):
... crypto = rsa.encrypt(message, pubkey)
... print "Ciphertext: %r" % crypto
... assert rsa.decrypt(crypto, privkey) == message
...
Ciphertext: "eYE\xab\x1c^z\xf2\x8f\xf7\xbc\xea\x06\x86e!'\xd9\x17=ElrU!\xfc\xb1l0\x0eU\x83\xa6j\x00\xe7\t\x1f8C\xefBA\x15\xf7\xd9\x9a\xfc\x04nw\xeb\xce\xa0\xbeCg\x85t\x99N`\xee\xe1"

所以我不希望它总是一样的。此外,您期望的字符串实际上是base64编码,这是另一个差异来源:
>>> 'SEcPB1mYNrfeE4zP4RI3z2K4Rh9HDNfPhuF28IyxHFjEOJ9Z+1zdIwPF0jsJGQDJyKpAju7dcYueHHXXeH8d+w=='.decode('base64')
