Even if you implement the PKI, there is still only the public and private key of the PKI, but no "CSR key". I can now check if any key is pressed anywhere else in the script by checking. If the data encoded by the base64 is one of the privatekey formats for which a PEM type is defined (TTBOMK PKCS1, PKCS8, OpenSSH-new, or PGP), you can convert it by breaking the base64 into lines of length 64 and adding BEGIN and END lines with the correct type, and maybe (for PGP) a few other things. As you can see, the PEM header contains the key type to be able to distinguish between key types and their respective encoding formats. DecryptKey(password.

The format only matters when installing the public key on the server (i. The easiest way to determine what type you have is to look at the certificate headers. As mentioned by Cody Gray in the comments, this method only fires on key strokes that have character information. Yes you will need the password to export the public key. The private key can be optionally encrypted using a symmetric algorithm. OpenSSL 3+ does not support PKCS1 by default and you will need use -traditional on the openssl rsa command.

I really don't want to generate the keys inside the iOS, the server will have another clients, such as laptop and Web Application and in a first stage the login (and RSA keys) are generated inside the WebApplication and sent encrypted to the Rest server. The Set<> would be much smaller than a HashMap, because it has to have the capacity of the maximum number of keys that can be pressed at the same time (suppose it's 10-20) instead of all the keys that can be pressed in a The APNS . But you should be aware that, even then, there is no guarantee that the round-trip from PKCS1 or PKCS8 bytes to Java objects and back to bytes will produce byte-for-byte identical representations.
