All nodes have the public key of every node that they know about. DSA was technically designed to be only a signature standard, but ways were developed after DSA was released to use any public-key signature algorithm for encryption. I think Freenet primarily uses DSA because at the time much of the crypto was being developed, RSA was still patented. -- ------- Timm Murray GPG Key: E4E143C6 Fingerprint: 591D DD8C 078C 7D45 ECE6 7B04 B62A 02C0 E4E1 43C6 -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCS d- s+: a-- C++(++++) UL++>++++ P+++>+++++$ L++>+++++$ !E W--@ N++@ !o !K w--- O@ M !V !PS !PE Y+(++) PGP+++ t@ 5+++ X@ R tv b++(++++) DI++@ D+(++) G e* h* r->r+++ y? ------END GEEK CODE BLOCK------
