Fixed a few issues in ADFGVX & Square ciphers, some performance improvement and fix a bad memory usage.

Here is v0.6 of old-crypto-rs.

Trying to fix a bug in one's code sometimes means... you forget to eat.

Of course, it just after doing a release that you find a bug (in the Playfair cipher).

v0.4.2 is now out.

#crypto #oldcrypto

[Blog] I have updated my post on the old pen-and-paper cryptographic systems following the v0.4.1 release.

It includes a fixed VIC Cipher implementation and a new SECOM implementation.

For those interested in old, paper-and-penvil kind of historical crypto systems, I re-implemented some of these long ago in Ruby and Go.

Now, in Rust as well, because, why not? :)
