Detailed Description

Use it instead of regular byte for any cheating-sensitive variables.

Regular type is faster and memory wiser comparing to the obscured one!
Feel free to use regular types for all short-term operations and calculations while keeping obscured type only at the long-term declaration (i.e. class field).

Member Function Documentation

Encrypt() [1/2]

static byte Encrypt ( byte  value, byte  key  )

inlinestatic

Encrypts passed value using passed key.

Key can be generated automatically using GenerateKey().

See also

Decrypt(), GenerateKey()

Encrypt() [2/2]

static void Encrypt ( byte[]  value, byte  key  )

inlinestatic

Encrypts passed value using passed key.

Key can be generated automatically using GenerateKey().

See also

Decrypt(), GenerateKey()

Decrypt() [1/2]

static byte Decrypt ( byte  value, byte  key  )

inlinestatic

Decrypts passed value you got from Encrypt() using same key.

See also

Encrypt()

Decrypt() [2/2]

static void Decrypt ( byte[]  value, byte  key  )

inlinestatic

Decrypts passed value you got from Encrypt() using same key.

See also

Encrypt()

FromEncrypted()

static ObscuredByte FromEncrypted ( byte  encrypted, byte  key  )

inlinestatic

Creates and fills obscured variable with raw encrypted value previously got from GetEncrypted().

Literally does same job as SetEncrypted() but makes new instance instead of filling existing one, making it easier to initialize new variables from saved encrypted values.

Parameters

encrypted	Raw encrypted value you got from GetEncrypted().
key	Encryption key you've got from GetEncrypted().

Returns

New obscured variable initialized from specified encrypted value.

GetEncrypted(), SetEncrypted()

GenerateKey()

static byte GenerateKey ( )

inlinestatic

Generates random key. Used internally and can be used to generate key for manual Encrypt() calls.

Returns

Key suitable for manual Encrypt() calls.

GetEncrypted()

byte GetEncrypted ( out byte  key )

inline

Allows to pick current obscured value as is.

Parameters

key	Encryption key needed to decrypt returned value.

Returns

Encrypted value as is.

Use it in conjunction with SetEncrypted().
Useful for saving data in obscured state.

See also

FromEncrypted(), SetEncrypted()

SetEncrypted()

void SetEncrypted ( byte  encrypted, byte  key  )

inline

Allows to explicitly set current obscured value. Crypto key should be same as when encrypted value was got with GetEncrypted().

Use it in conjunction with GetEncrypted().
Useful for loading data stored in obscured state.

See also

FromEncrypted()

GetDecrypted()

byte GetDecrypted ( )

inline

Alternative to the type cast, use if you wish to get decrypted value but can't or don't want to use cast to the regular type.

Returns

Decrypted value.

RandomizeCryptoKey()

void RandomizeCryptoKey ( )

inline

Allows to change current crypto key to the new random value and re-encrypt variable using it. Use it for extra protection against 'unknown value' search. Just call it sometimes when your variable doesn't change to fool the cheater.

Implements IObscuredType.
