directory, and PKIs match these to identities using (*) certificates.
The Rijndael schedule allows for the creation of round ones of these tools. An important problem involving these tools was addressed by the Diffie-Hellman protocol, which allowed for the exchange of these things. PGP uses both symmetric and asymmetric types of these things while AES uses only one of these. These things are stored in the .ssh ["dot s s h"] directory, and PKIs match these to identities using (*) certificates. In a popular scheme, one of these things is constructed as the product of two large prime numbers and is published, though the two prime factors themselves are kept secret. For 10 points, name these tools used for RSA that come in public and private forms and are used to encrypt and decrypt messages.
