What is the difference between pubKey and PubKeyPEM?

QUESTION

What is the difference between pubKey and PubKeyPEM?

Asked 2020-Jul-23 at 10:45

I am learning the RSA encryption algorithm, and I want to use that in Python. I'm using the pycryptodome package, and I can see from there that there are two private keys variables.

What is the difference between pubKey and pubKeyPEM, and which of them I need to use for the encryption part?

Also, why the Decryptor use both of the keys (keyPair) instead of the private key (privKeyPEM) ?

...

pubKey is just the presentation of the key as usable by Python. It consists of two integers: the modulus and the public exponent. Of course, it could e.g. also be a reference to a key in a hardware device, where applicable.

pubKeyPEM is a specific encoding of the public key in bytes or characters. It's a SubjectPublicKeyInfo structure according to the API specifications. SubjectPublicKeyInfo or SPKI is a binary structure, PEM is an ASCII armor around that, i.e. it specifies the structure and then encodes the binary using base 64. It's commonly used by e.g. OpenSSL.

For the encryption part you need the pubKey. But you probably have to transport the pubKey to the sender first, or you may have to store the pubKey in a DB or filesystem. That's where the export functionality comes in.

The private key generally contains the public key (as public exponent field), or it is easy to calculate it from the private key (in case of an Elliptic Curve key). So you might as well think of the private key as the key pair. It depends on the library if the concepts can be used interchangeably.
