Colm MacCarthaigh 08e578c421 Don't include locked memory in coredumps 
Linux 3.4+ supports a DONTDUMP advisory, which prevents memory
from being included in coredumps.

Frank Denis c8dfd0d211 _detached versions of crypto_box 2014-06-26 15:54:03 -07:00
Frank Denis 44f7a9f3cb Allow the authentication tag to be stored separately from the message. 
Encrypting in-place and storing the tag separately is a very common need.
Instead of forcing people to do their own cuisine, let's provide simple
variants of the _easy interfaces to do that.

Frank Denis a7410966ea Rename secretbox_chacha20poly1305() -> aead_chacha20poly1305() 
The tag is still at the end. This will be changed right after.

Frank Denis 957315035a Use weak symbols to prevent LTO if this is an option. 
Idea from Matthew Dempsky.

Frank Denis c7418dfd58 zero the poly1305 state in crypto_secretbox_chacha20poly1305* 2014-06-20 16:28:00 -07:00
Frank Denis bd1490a6cd Add AEAD_CHACHA20_POLY1305 
With a twist: in order to be consistent with the crypto_stream
interface, the tag has to come before the ciphertext.

Frank Denis bc11c90bf5 Merge branch 'master' of github.com:jedisct1/libsodium 
* 'master' of github.com:jedisct1/libsodium:
  Avoid naming a function select() in order to avoid confusion with select(2)
  Comment dead code generated by qhasm
  Remove useless access() before open()
  Add annotations for Coverity FPs
  test/default/sign.c: make the test vectors static
  Make crypto_sign() test code more explicit. crypto_sign() doesn't just need the secret key. The public key has to follow. Which is why the test vectors are laid out in this order. But this can confuse static analysis, as well as people looking at the test in order to better understand how crypto_sign() works. So, just copy the sk and the pk into a dedicated buffer, for clarity.
  Disable the pwhash_scrypt_ll test that requires 1 Gb RAM. This is way too much for many devices and for VPS users.

Frank Denis 7b7e223d39 Do not allocate more memory than needed in the easy interfaces. 
And compute m_boxed_len as (ZEROBYTES || message len) to match the way the
documentation describes the output.

Frank Denis 6aacecac60 Rename curve25519/ref10 files to avoid duplicate file names. 
Sharing code between curve25519 and ed25519 would be way better, but
until then, having distinct file names is required for Cocoapods, and makes
things easier in Visual Studio.
