Detailed Description

SHA-256 hash function class.

Member Function Documentation

virtual void uicore::SHA256::add ( const void *  data, int  size  )

pure virtual

Adds data to be hashed.

virtual void uicore::SHA256::add ( const DataBufferPtr &  data )

pure virtual

Add.

Parameters

data	= Data Buffer

virtual void uicore::SHA256::calculate ( )

pure virtual

Finalize hash calculation.

static std::shared_ptr<SHA256> uicore::SHA256::create ( )

static

Constructs a SHA-256 hash generator.

virtual std::string uicore::SHA256::hash ( bool  uppercase = false ) const

pure virtual

Returns the calculated hash.

virtual void uicore::SHA256::hash ( unsigned char  out_hash[hash_size] ) const

pure virtual

Get hash.

Parameters

out_hash

= where to write to

virtual void uicore::SHA256::reset ( )

pure virtual

Resets the hash generator.

virtual void uicore::SHA256::set_hmac ( const void *  key_data, int  key_size  )

pure virtual

Enable a HMAC based calculation.

Call this function before the initial add(). It is reset by reset()

Parameters

key_data	= The HMAC key
key_size	= The size of the key_data
