I've fixed several things in both LTM/LTC. In LTC I fixed a bug in rsa_exptmod where if you threw a random "key type" at it it would always just use the "d"...
Hi Tom Before you release next LTM you might want to fix these two small warnings that bcb 5.51 gave me: Warning W8004...

Hi, I have been using (a derivative of) rsa_make_key to create an RSA keypair. When I attempted to use the key with another piece of software I discovered that...

Regarding the primes of being one bit longer the point was when you say "I have a k-bit prime" it should be a prime larger than 2^k not 2^ {k-1} as in the case...
Ok, I went a bit mad over the last couple of weeks. If you ever watch a cartoon called Invader Zim beware! So I have exams this week [one today in 24 mins]....
I sped up da hash code by making it able to compress data from source buffers. So if there are no bytes in the state and you pass it a buffer >= the block...
You mean that if I assemble a packet, encrypt it, call SHA-1 on it, and append the hash, that the packet buffer will have been altered? I don't consider this...

For the worried....tv_gen emits the same hash_tv.txt file with the new SHA-1 code as before [it tests messages from 0 to 128 bytes long, double the block...
Fishing around I found a Crypto'95 paper on fast ECC. It has the "almost inverse" algo. I want to try it out. The goal here though will be to cut down...

I've just added DSA to the list of PK that LTC supports. I still have to write key export/import routines but the sign/verify works already. A 160/512 key can...
