- Reorganized the code a bit and split each of sigtool's
commands into a separate file.
- Added extra tests to validate verify's new capabilities
- Updated README
* update build script to use a diff go-root
* update tests.sh to use diff go-root
* move pflag to opencoff/pflag
* use common lib to parse string size..
* bugfix: use os.IsNotExist() instead of comparing errors for equality;
this fixes incorrect handling of missing authorized_keys file.
* move die() and warn() into die.go - and make them public functions.
* teach die.go to also provide atexit() like functionality
* teach all callers of sign.SafeFile{} to use AtExit() to delete
temporary artifacts
* symbol renaming: die->Die, warn->Warn.
* Added new SafeFile (io.WriteCloser) class + methods to atomically write a file.
* Teach core lib to use SafeFile for all file I/O
* Teach sigtool to use SafeFile for all file I/O
* Cleaned up the public interfaces of sign/ to be more coherent:
- with uniform APIs for marshaling, unmarshaling, serialization.
- removed KeyPair class/interface and stick to PrivateKey as the primary
interface.
* collected common rand utility functions into rand.go
* Teach sigtool to NOT overwrite existing output files (keys, signatures etc.)
* Teach sigtool to use a new --overwrite option for every command that creates
files (generate, sign, encrypt, decrypt)
* encrypt/decrypt will try to use the input file mode/perm where possible
(unless input is stdin).
* Added more tests
