making it impossible to change a secure key passphrase

Boris Epstein asked:

According to this:

How do I change my private key passphrase?

it is possible to change your private RSA/DSA key passphrase any time. Is there a way to generate a key with a passphrase that is set once and can not be altered?

My answer:


No, and the question doesn’t make sense either. There is no reason for this. A private key is just that.
