Member Enumeration Documentation

◆ IV_Requirement

Secure IVs requirements as enumerated values.

Provides secure IV requirements as a monotonically increasing enumerated values. Requirements can be compared using less than (<) and greater than (>). For example, UNIQUE_IV < RANDOM_IV and UNPREDICTABLE_RANDOM_IV > RANDOM_IV.

Objects that use SimpleKeyingInterface do not support an optional IV. That is, an IV must be present or it must be absent. If you wish to support an optional IV then provide two classes - one with an IV and one without an IV.

Enumerator
UNIQUE_IV 

The IV must be unique.

RANDOM_IV 

The IV must be random and possibly predictable.

UNPREDICTABLE_RANDOM_IV 

The IV must be random and unpredictable.

INTERNALLY_GENERATED_IV 

The IV is set by the object.

NOT_RESYNCHRONIZABLE 

The object does not use an IV.

iva block of bytes to receive the IV

The IV must be at least IVSize() in length.

This method should be called after you finish encrypting one message and are ready to start the next one. After calling it, you must call SetKey() or Resynchronize(). before using this object again.

Internally, the base class implementation calls RandomNumberGenerator's GenerateBlock()

Note

pure virtual

Returns a valid key length for the algorithm.

Parameters
keylengththe size of the key, in bytes
Returns
the valid key length, in bytes

keylength is provided in bytes, not bits. If keylength is less than MIN_KEYLENGTH, then the function returns MIN_KEYLENGTH. If keylength is greater than MAX_KEYLENGTH, then the function returns MAX_KEYLENGTH. if If keylength is a multiple of KEYLENGTH_MULTIPLE, then keylength is returned. Otherwise, the function returns a lower multiple of KEYLENGTH_MULTIPLE.

const byte iv 
)
inline

Sets or reset the key of this object.

Parameters
keythe key to use when keying the object
lengththe size of the key, in bytes
ivthe initialization vector to use when keying the object

SetKeyWithIV() calls SetKey() with a NameValuePairs() object that only specifies iv. iv is a byte buffer, and it must have a size IVSize().

Definition at line 708 of file cryptlib.h.

◆ SetKeyWithIV() [2/2]

void SimpleKeyingInterface::SetKeyWithIV ( const byte key,
size_t  length,
const byte iv,
size_t  ivLength 
)

Sets or reset the key of this object.

Parameters
keythe key to use when keying the object
lengththe size of the key, in bytes
ivthe initialization vector to use when keying the object
ivLengththe size of the iv, in bytes

SetKeyWithIV() calls SetKey() with a NameValuePairs that only specifies IV. The IV is a byte buffer with size ivLength. ivLength is an integer parameter, and -1 means use IVSize().

Definition at line 69 of file cryptlib.cpp.

◆ SetKeyWithRounds()

void SimpleKeyingInterface::SetKeyWithRounds ( const byte key,
size_t  length,
int  rounds 
)

Sets or reset the key of this object.

Parameters
keythe key to use when keying the object
lengththe size of the key, in bytes
roundsthe number of rounds to apply the transformation function, if applicable

SetKeyWithRounds() calls SetKey() with a NameValuePairs object that only specifies rounds. rounds is an integer parameter, and -1 means use the default number of rounds.

◆ ThrowIfInvalidIV()

void SimpleKeyingInterface::ThrowIfInvalidIV ( const byte iv)
protected

Validates the IV.

Parameters
ivthe IV with a length of IVSize, in bytes
Exceptions
InvalidArgumenton failure

Internally, the default implementation checks the iv. If iv is not NULL or nullptr, then the function succeeds. If iv is NULL, then IVRequirement is checked against UNPREDICTABLE_RANDOM_IV. If IVRequirement is UNPREDICTABLE_RANDOM_IV, then then the function succeeds. Otherwise, an exception is thrown.

Definition at line 86 of file cryptlib.cpp.

◆ ThrowIfInvalidIVLength()

size_t SimpleKeyingInterface::ThrowIfInvalidIVLength ( int  length)
protected

Validates the IV length.

Parameters
lengththe size of an IV, in bytes
Exceptions
InvalidArgumentif the IV length is invalid

Definition at line 92 of file cryptlib.cpp.

◆ ThrowIfInvalidKeyLength()

void SimpleKeyingInterface::ThrowIfInvalidKeyLength ( size_t  length)
protected

Validates the key length.

Parameters
lengththe size of the keying material, in bytes
Exceptions
InvalidKeyLengthif the key length is invalid

Definition at line 74 of file cryptlib.cpp.

◆ ThrowIfResynchronizable()

void SimpleKeyingInterface::ThrowIfResynchronizable ( )
protected

Validates the object.

Exceptions
InvalidArgumentif the IV is present

Internally, the default implementation calls IsResynchronizable() and throws InvalidArgument if the function returns true.

Note
called when no IV is passed

◆ UncheckedSetKey()

virtual void SimpleKeyingInterface::UncheckedSetKey ( const byte key,
unsigned int  length,
const NameValuePairs params 
)
protectedpure virtual

Sets the key for this object without performing parameter validation.

Parameters
keya byte buffer used to key the cipher
lengththe length of the byte buffer
paramsadditional parameters passed as NameValuePairs

key must be at least DEFAULT_KEYLENGTH in length.
