Detailed Description

Private key encryption is done based on a CMasterKey, which holds a salt and random encryption key.

CMasterKeys are encrypted using AES-256-CBC using a key derived using derivation method nDerivationMethod (0 == EVP_sha512()) and derivation iterations nDeriveIterations. vchOtherDerivationParameters is provided for alternative algorithms which may require more parameters (such as scrypt).

Wallet Private Keys are then encrypted using AES-256-CBC with the double-sha256 of the public key as the IV, and the master key's key as the encryption key (see keystore.[ch]).Master key for wallet encryption
