src/key.cpp

Large amount of code added and removed. Examples of code replaced.

+#include <map>

Code replaced

 -#include <openssl/bn.h>

 -#include <openssl/rand.h>

Code removed

 +void CKey::SetCompressedPubKey(bool fCompressed)
 +    EC_KEY_set_conv_form(pkey, fCompressed ? POINT_CONVERSION_COMPRESSED : POINT_CONVERSION_UNCOMPRESSED);
 +    fCompressedPubKey = true;

Complete functions replaced

 +void CKey::Reset()

 +CKey::CKey(const CKey& b)

  +bool CKey::SetPrivKey(const CPrivKey& vchPrivKey)

  +    const unsigned char* pbegin = &vchPrivKey[0];

 +bool CKey::SetSecret(const CSecret& vchSecret, bool fCompressed

 +CSecret CKey::GetSecret(bool &fCompressed) const

 +CPrivKey CKey::GetPrivKey() const

  +CPubKey CKey::GetPubKey() const

Various functions replaced

 +// create a compact signature (65 bytes), which allows reconstructing the used public key
 +// The format is one header byte, followed by two times 32 bytes for the serialized r and s values.
  +// The header byte: 0x1B = first key with even y, 0x1C = first key with odd y,
  +//                  0x1D = second key with even y, 0x1E = second key with o   

  +bool CKey::SignCompact(uint256 hash, std::vector<unsigned char>& vchSig)
