New in release 1.3: - bug fixex. - The files SSHDSAHostskeys.Text and SSHRSAHostkeys.Text got merged to SSHHostkeys.Text. - New module cryptPrimes.Mod for generating large safe prime numbers. - Module cryptDSA is finished (includes signing now). - Improved performance. I've tuned the performace of multi pecision integers (cryptBigNumbers.Mod). The time for establishing a SSH- connection, which is mainlly determined by the computation of '(a^p) mod m' in the Diffie Hellman key exchange, could be reduced by a factor of nearly three but is still more than two times greater than with the original SSH. This was the first time I really missed unsigned integer types in the Oberon language. In the old implementation of cryptBigNumbers multi precision integers had been represented by 8 bit digits because of ease of coding (no overflow- and sign problems when computing the values in LONGINT). In the new implementation the 'digits' are 32 bit. Unfortunateley a lot of the benefit of using larger digits gets lost by the additional effort for treating the sign bit and overflow conditions. With the availability of the Modula2 CARDINAL type (and CARDINAL64) coding would have been much easier and (still more important) the code would have been faster.
