Conversely, I had listed Vaclav Ovsik in the credits for the Perl-XS
wrapper, but not in the license.

precompute only as needed, or will want to access some other expensive
resource or etc.
Change how the secret for generating blinding is done in cases where a
PRNG isn't available. Use the operations public op to hide the secret,
for instance the seed for a DH blinding variable is 2^x mod p.
Make use of being able to mutate internal structures in the RW signer,
since that does have access to a PRNG, so use it to initialize the
blinder on first call to sign().

PK_Encryptor_EME and PK_Decryptor_EME; the message recovery is somewhat
implicit in the recovery of the plaintext.

Remove use of look_pk from the source and examples, instead
instantiate classes directly.

performed. Up until now, each key object (eg DSA_PublicKey or
ECDH_PrivateKey) had two jobs: contain the key material, and know how
to perform any operations on that key. However because of a desire to
support alternative implementations (GNU MP, hardware, whatever),
there was a notion of operations, with the key objects containing an
op that they got via engine rather than actually implementing the
underlying algorithms directly.
Now, represent the operation as an abstract interface (typically
mapping a byte string to a byte string), and pass a plain Public_Key&
or Private_Key& to the engine. The engine does any checks it wants (eg
based on name, typeid, key sizes, etc), and either returns nothing
(I'll pass) or a pointer to a new operation that represents signatures
or encryption or what-have-you using that key.
This means that plain key objects no longer contain operations. This
is a major break with the traditional interface. On the other hand,
using these 'bare' operations without padding, KDFs, etc is 99% of the
time a bad idea anyway (and if you really need them, there are options
so you get the bare op but via the pubkey.h interfaces).
Currently this change is only implemented for DH and ECDH (ie, key
agreement algorithms). Additionally the optional engines (gnump and
openssl) have not been updated. I'll probably wait to touch those
until after I can change them all in one go for all algos.

I'm not sure where the old name came from though as literally the only
hits for it on Google are botan-related.

I'll officially kill off Ajisai (instead of it just lingering as a zombine
as it is currently).
Apparently I broke something (or multiple things) during the import process;
servers crash and clients gets MAC errors on connect.

finalized.
Move header to passhash9.h and rename the functions to be passhash9
specific ({generator,check}_passhash9)
Add an algorithm identifer field. Currently only id 0 is defined, for
HMAC(SHA-1), but this opens up for using HMAC(SHA-512) or HMAC(SHA-3)
or CMAC(Blowfish) or whatever in the future if necessary. Increase the
salt size to 96 bits and the PRF output size to 192 bits.

extant for a long long time and was never caught because until
recently the code did not depend on M.size(). However with the recent
loadstore changes that use memcpy to load the entire array in one
shot, an extra 128 bytes of memory would be read (but not used) in
each iteration.
This probably did not cause any problems except for Valgrind warnings,
though in some situations it would be possible for the M buffer and
MDx_HashFunctions buffer to be close enough that memcpy would be called
with overlapping regions, which could cause arbitrarily weird failures
since memcpy is allowed to assume they do not overlap.

password hashing schemes.
Increase salt size to 80 bits.
Research shows that virtually no other PBKDF2 implementations support
anything but SHA-1; for ease of implementation elsehwere switch back
from SHA-512 to SHA-1. Should be mostly harmless; it limits total
entropy of the password to a maximum of 160 bits, but this is unlikely
anyway.
Use two bytes to specify the work factor for future-proofing.
Add a test.

the passhash example to the library. Support variable work factors;
default work factor of 10 takes about half a second to do one password
on my Core2. Switch to using SHA-512 instead of SHA-1 in PBKDF2. To keep
the output evenly sized for base64 purposes, reduce PBKDF2 output size by
one byte (to 112 bits).
