I'm new to cryptography so please bear with me.
If I create 2048-bit keys and export security key to file key.gpg (so without ASCII armor), I get a file with size of 1.28 kB.
If I understand it correctly, the 2048-bit key means a random string of ones and zeros with a length of 2048 characters. So why the filesize is so different?
If I export security key to key.asc (with ASCII armor) and then decode the actually key part with base64 to binary decoder, I get a string of ones and zeros with 20856 characters.
What am I missing and how can I view the actually security key in ones and zeros?
