Detailed Description

This is the base class for access policies and credentials.

Delegated rights are specified by a public key, which is signed by an object already possessing those rights.

Constructor & Destructor Documentation

PolCredBase::PolCredBase (  const RSAPublicKey &    publicKey, const RSAPrivateKey &    signingKey, const HashFunction &    hashFunc )

Create PolCredBase from public and private keys and a hash function. Parameters: publicKey  The public key receiving delegated rights. signingKey  The private key used to delegate the rights. hashFunc  The function used to create a digest of publicKey. Exceptions: BignumNullException  An error occurred allocating a new BIGNUM. BignumBin2BNException  An error occurred translating a character array to a BIGNUM. Definition at line 37 of file PolCredBase.cc. References CODEX_Ciphers::RSAPrivateKey::sign(), and signature().

Member Function Documentation

bool PolCredBase::verify (  const RSAPublicKey &    delegator, const HashFunction &    hashFunc )  const

Verify against a known public key. Parameters: delegator  The public key of the rights granter. hashFunc  The hash function used to make a digest of the public key. Returns: Success or failure of signature verification. Definition at line 80 of file PolCredBase.cc. References CODEX_Ciphers::RSAPublicKey::verifySignature().
