Fix zlib error when compressing an empty buffer
|
| |
| |
| |
| |
| | |
zlib treats a nullptr output buffer as an error. This commit fixes the
failing compression tests.

&emptyVector[n] triggers undefined behavior because it is an out-of-
bounds access, even if n == 0. emptyVector.data() does not (but may
return nullptr).

Add PKCS#8 private/public key processing tool GH #163

This tool works similar to 'openssl pkey' in that it allows to
read a private key from file and output the private or
corresponding public key to file. It also allows changing a
private key passphrase this way. This tool comes in handy when
replacing use of openssl in scripts.
The syntax is:
botan pkcs8 --in=private.pem --out=key_out.pem [--pubout] [--passin=] [--passout=] [--pbe=]

missing on Solaris at least. On such systems it's probably safe to
assume that no amount of memory can be mlock'ed from userspace, so
just return zero to disable the allocator entirely.

handle non-ASCII in a way that is compatible with Python 2.7 and 3 at
the same time.

rather than after. After blinding the value is always reduced mod n
so the condition is never met.
This may be the cause of RSA test failures described in GH #174
The scenario was that during randomized corruption tests we
occasionally provide an input which was greater than the modulus.
When that happened the value was effectively reduced mod n, so the
self-check would later fail, because the decrypted result (reduced mod n)
would be compared with the original (larger than n) input.

The plain PointGFp operator* now uses Montgomery ladder exclusively.
Adds a blinded point multiply algorithm which uses exponent and point
randomization, as well as a Montgomery ladder technique that takes a
random walk of the possible addition chains for k.

On systems where unsigned long is uint64 (typically 64 bit systems), a
string containing a number greater than 2^32-1 was sucessfully converted
to a uint64 and than reduced to uint32, causing an overflow. E.g.
to_u32bit("4294967296") was 0 and to_u32bit("4294967297") was 1.
