Wait for already running threads if a thread creation failed.
Use explicit_bzero() on recent glibc versions.
(Without fixed logic, we have already macro definition through automake.)
Fixes#444.
rename sector_start -> iv_start (it's now a iv shift for subsequent
en/decrypt operations)
rename count -> length. We accept length in bytes now and perform sanity
checks at the crypt_storage_init and crypt_storage_decrypt (or encrypt)
respectively.
rename sector -> offset. It's in bytes as well. Sanity checks inside
crypt_storage functions.
Note: it is always better to use external libargon2 library.
Unfortunately, until Argon2 is in generic crypto libraries,
we must sometimes use bundled version just for bureaucratic reasons.
Let's include optimized variant of reference implementation as well.
Note, this code will not add any SSE compiler switches.
If --enable-internal-sse-argon2 option is used, it checks if current
compilation flags support simple SSE progam and if so, it use
the optimized variant.
(Not tested for AVX optimizations; it expects that SSE is enabled as well.)
For now, crypto API quietly used cipher witout IV if a cipher
algorithm wihtou IV specificaton was used (e.g. aes-xts).
This caused fail later during activation.
This patch allows only two specific backed use without specified IV
(ECB mode and NULL cipher).
Also check cipher string early during parsing of CLI options.
1) If the calculated costs were the same, it run forever.
2) If the calculation returned final values in the first step,
out costs were not updated and benchmark returned too low values.
When we have measured time smaller than target time, we are decreasing
the parameters. Thus, we should first try to decrease t_cost and only
if that is not possible should we try to decrease m_cost instead. The
original logic was only valid for the case where parameters are being
increased. Most notably this caused unusual parameter combinations for
iteration time < 250 ms.
In this commit we also factor out the now heavily nested parameter
update formula.
