TCrypto Class Reference
Some builds of the crypto library have restrictions that only allow weak ciphers to be used. This class provides static helper functions for determining these restrictions.
Member Functions Documentation
IsAsymmetricWeakEnoughL(TInt)
| IMPORT_C TBool | IsAsymmetricWeakEnoughL | ( | TInt | aAsymmetricKeyBits | ) | [static] |
Indicates whether an asymmetric key is small enough to be allowed. Note that this function leaves if the key is too large - in other words it can never return EFalse.
-
leave
- KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library.
Parameters
| TInt aAsymmetricKeyBits | The size (in bits) of the asymmetric key |
IsSymmetricWeakEnoughL(TInt)
| IMPORT_C TBool | IsSymmetricWeakEnoughL | ( | TInt | aSymmetricKeyBits | ) | [static] |
Indicates whether a symmetric key is small enough to be allowed. Note that this function leaves if the key is too large - in other words it can never return EFalse.
-
leave
- KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library.
Parameters
| TInt aSymmetricKeyBits | The size (in bits) of the symmetric key |
Strength()
Gets the allowed cipher strength.
