aside from the addition of OpenSSL support a few other changes have been included:
- setEngine(), as added by petrich, is depricated (not that it was ever in trunk to begin with)
it has been replaced with isValidEngine() and setPreferredEngine().
- replace _generate_xor() with increment_str()
_increment_str() had extra functionality that wasn't being used. ie. it could concatenate
multiple successive string increments to one another automatically. but not only was that
functionality not used - it also made the function less versatile. _increment_str() can be
used more easily for iterative brute forcing (for example)
- rename Crypt_Base::_stringShift to Crypt_Base::_string_shift (for consistency)
- more expansive unit test coverage
Random: include the Crypt_* classes if they're available
* bantu/a-random-change:
phpseclib_is_includable() -> phpseclib_resolve_include_path()
Drop Net_SSH2::_is_includable() method.
Random: a few changes to the stream_resolve_include_path_function
Replace stream_resolve_include_path with phpseclib_is_includable.
Random: add explanatory comment
SSH2: replace _is_includable() with stream_resolve_include_path
Random: include the Crypt_* classes if they're available
RSA: add support for PKCS8 encoded private keys
* terrafrost/pkcs8:
Crypt/Base: readability improvement
RSA: CS adjustments
RSA: rename PUBLIC_FORMAT_PKCS1_RAW -> PUBLIC_FORMAT_PKCS8
RSA: add PKCS8 unit tests
RSA: add support for saving encrypted PKCS8 keys
Crypt/Base: adjust default key size for pbkdf1
RSA: add support for loading PKCS8 encrypted private keys
Crypt/Base: add support for pbkdf1
RSA: add support for saving to PKCS8 (unencrypted)
CRYPT_RSA_PUBLIC_FORMAT_PKCS1_RAW and CRYPT_RSA_PUBLIC_FORMAT_PKCS1
produce two very similar looking keys but they are not the same.
As dissection OpenSSL's asn1parse would reveal CRYPT_RSA_PUBLIC_FORMAT_PKCS1
has the fact that it is an RSA key embedded within it whereas
CRYPT_RSA_PUBLIC_FORMAT_PKCS1_RAW does not. phpseclib now resolves
this ambiguity in the same way that OpenSSH's ssh-keygen does.
Despite this change CRYPT_RSA_PUBLIC_FORMAT_PKCS1_RAW is still incompatible
with OpenSSL's rsautl (CRYPT_RSA_PUBLIC_FORMAT_PKCS1 is compatible). I guess
this incompatibility isn't just due to the headers but is also due to the
overall structure of the format.
bad timezone settings can make phpinfo() throw errors so we'll just
suppress them. if there are legit non-timezone errors with php install
those will probably be hit in other parts of the code
