Merge pull request #660 from levitte/no-BCryptGenRandom 
Make the definition of LTC_WIN32_BCRYPT private
 2024-08-26 14:49:35 +02:00
Richard Levitte
00708c8837 Make the definition of LTC_WIN32_BCRYPT private 
1. It's internal anyway, so doesn't quite need to be reflected in a
   public header file.
2. This makes it easy for someone build this library to choose not
   to use BCryptGenRandom() by simply definining LTC_NO_WIN32_BCRYPT,
   which was hard to reflect in an unmodified public header file.

Alternative to #653

c0be0aa0bf Add support for more types of encrypted PEM files 
1. ChaCha20, two-key 3DES and DES-X encrypted OpenSSL PEM files

2. AES-GCM and Chacha20+Poly1305 encrypted SSH keys

* OpenSSH uses a slightly different algorithm for its
  `chacha20-poly1305@openssh.com` than defined in the RFC.
  Therefore add an `openssh_compat` flag to
  `chacha20poly1305_state`.
* Add the option to give a 16byte IV and no counter, when calling
  `chacha20poly1305_memory()`
* Add support for DES-X

95790221fb Add free() function to password_ctx 
The user can now pass a `free()` function pointer that will be used to
free the memory that has been allocated by the `callback()`.
If `free()` is NULL, the library will still call `XFREE()`.

03515d5611 Move password buffer into the library 
The design before was not completely fine. The user had to allocate the
buffer and passed ownership to the library.
As of [0] this seems to be a problem in some environments.
