Solaris is showing unusual signs with SunCC 5.13 and 5.14. One user is experiencing a SIGBUS in SHA512::Transform due to data alignment of 'data', which was only 2-byte aligned. The project experienced an exception "Coneable not implemented" during the hashing test after building with Cmake. Its not clear how much Cmake influenced the project's results.
Recent versions of clang warn about missing PKCS_DigestDecoration
definitions, specifically the decoration members. For example:
In file included from testpkcs.cpp:8:
./pkcspad.h:89:53: warning: instantiation of variable 'CryptoPP::PKCS_DigestDecoration<CryptoPP::SHA1>::decoration' required here, but no definition is available [-Wundefined-var-template]
return HashIdentifier(PKCS_DigestDecoration<H>::decoration, (size_t)PKCS_DigestDecoration<H>::length);
^
./pubkey.h:608:19: note: in instantiation of member function 'CryptoPP::PKCS1v15_SignatureMessageEncodingMethod::HashIdentifierLookup::HashIdentifierLookup2<CryptoPP::SHA1>::Lookup' requested here
return L::Lookup();
^
./pubkey.h:638:26: note: in instantiation of member function 'CryptoPP::TF_ObjectImplBase<CryptoPP::TF_VerifierBase, CryptoPP::TF_SignatureSchemeOptions<CryptoPP::TF_SS<CryptoPP::PKCS1v15, CryptoPP::SHA1, CryptoPP::RSA, int
CryptoPP::RSA, CryptoPP::PKCS1v15_SignatureMessageEncodingMethod, CryptoPP::SHA1>, CryptoPP::RSAFunction>::GetHashIdentifier' requested here
class CRYPTOPP_NO_VTABLE TF_ObjectImpl : public TF_ObjectImplBase<BASE, SCHEME_OPTIONS, KEY_CLASS>
^
./pkcspad.h:32:20: note: forward declaration of template entity is here
static const byte decoration[];
^
This is because pkcspad.h doen't contain explicit instantiation
declarations for PKCS_DigestDecoration. These warnings can be fixed by
adding them in the !CRYPTOPP_IS_DLL case, which appears to apply only to
Windows.
__BIGGEST_ALIGNMENT__ is provided by some compilers, like GCC and ICC (but not Clang). It is usually 16 on 64-bit platforms; and it is usually 8 on 32-bit platforms
