Mirek Kratochvil 9c9e49ae7b fmtseq: forgotten include 2013-05-25 20:03:42 +02:00

Mirek Kratochvil b5ae7ca4dd algos_sig: added H=20 fmtseq variant 
...that provide around 1 million signatures per key. That seems more
than sufficient for human usage.

Note that generating the key takes 16 times longer than for already
present algorithms (that have H=16). On my computer, it is around 4
minutes for fmtseq128N20 and 16 minutes for fmtseq256N20.

Mirek Kratochvil 0980ee827a sha2: fix the ugly warning 
memcpy() is better than dereferencing a type-punned-pointer for
simulating memcpy()

Mirek Kratochvil 18449bdc8a arcfour: greatly increase discard parameters 
Okay, this thing got public so it's time to make the RC4 rugged. Not
that I'd know about something that would break current implementation,
but it's nice to at least do the recommended discard correctly.

We'll probably be adding better symmetric ciphers anyway.

Note that this is an incompatible change (again). FMTSeq private keys
will need to be replaced. Existing signature validity doesn't change.
Encrypted messages will not be possible to decrypt.

Mirek Kratochvil 8c185c51ad mce_qd: compute check matrix on the fly 
codecrypt is usually invoked only with one prepare() and decrypt(), so
this basically saves several megs of memory and cuts needed computation
time in half.

Mirek Kratochvil 63d51911f9 algos_enc: also pad beginning of the message 
to avoid possible known plaintext attacks on the symmetric cipher when
beginning of the ciphertext is known (which is a common situation, e.g.
when sign+encrypting)

Mirek Kratochvil 24bd5bd185 algos_sig: new support for fmtseq192 
It's quite rational to have such algorithm. 256-bit security is usually
an overkill, and this has two times smaller signatures (around 9.5kB) is
_so_ much faster. Use it.

This reverts commit 83e0e3ad58.

The logic behind removing clearsign was somehow flawed by momentary
indisposition.

Mirek Kratochvil 83e0e3ad58 main: remove clearsign option 
Clearsigning is how we do signatures by default now. Detached signature
file stays as an option. Having a PGP-like non-cleartext non-detached
file doesn't really look much useful and brings complexity. Axed.
