一般.pem,.cer,.crt,.key的文本文件可根据响应PEM标识推测其内容、格式及加密/未加密。 除了明显PEM格式文件的扩展名通常是.pem,.cer,.crt,.key等多种; DER格式文件扩展名通常为.der,也可以是.cer,.crt等,主要通过文件内容格式判断(是否文本格式,是否有PEM标识)是PEM还是DER格式。 常见PEM格式标识 数字证书 ...

I have a test that creates an encrypted rsa key and then tries to load and decrypt it withload_pem_private_key, using an invalid password and asserting the error message"Bad decrypt. Incorrect password?". Every now and then my test fails, because I get a different error message, i.e....
I'm using cryptophy 36.0.0, and trying to use it to load private key from pem file. When I use load_pem_private_key(pem.encode(), password=None) to load pem file, the pem data is in PKCS#8 v2 format, RFC 5958: ---BEGIN PRIVATE KEY---...
I have not found a way to load an RSA private key from a PEM file to use it in python-crypto (signature). python-openssl can load a PEM file but the PKey object can't be used to retrieved key information (p, q, ...) to use with Crypto.PublicKey.construct()....

However, theload_der_private_keyfunction expects to be given a key in DER format (as raw bytes). That function can't handle a key in PEM format and that's why it throws the error. To fix, either pass the content of the PEM file toload_pem_private_keyinstead ofload...
