I'm new to cryptography, and I was making an experiment a few minutes ago, but I want to have some deeper knowledge about RSA public and private keys.
I have a set of keys
One begins with
-----BEGIN RSA PRIVATE KEY----- MIIBOgIBAAJBAOlnH1jZ2YLfWuYMop1a4N9jsUPK...... -----END RSA PRIVATE KEY-----
and another with
-----BEGIN PUBLIC KEY----- MFowDQYJKoZIhvcNAQEBBQADSQA.... -----END PUBLIC KEY-----
I've parsed them using Java and I can make use of them, as RSA private and public keys respectively.
But the question I have is....
Are there some checksum mechanisms built into RSA keys ?
I ask this because, I'd like to know what happens if, by error or intentional, one or more characters from the encoded PEM are modified. Does this breaks the key ? Or changes the key internally, without breaking it ?
