Member Attribute Documentation

iPadding

CPaddingPKCS1Encryption *iPadding[protected]

The PKCS#1 v1.5 encryption padding

iPublicKey

const CRSAPublicKey &iPublicKey[protected]

The RSA public key

Constructor & Destructor Documentation

CRSAPKCS1v15Encryptor ( const CRSAPublicKey & )

CRSAPKCS1v15Encryptor(const CRSAPublicKey &aKey)[protected]

~CRSAPKCS1v15Encryptor ( void )

~CRSAPKCS1v15Encryptor(void)[virtual]

The destructor frees all resources owned by the object, prior to its destruction.

Member Function Documentation

ConstructL ( void )

voidConstructL(void)[protected]

EncryptL ( const TDesC8 &, TDes8 & )

voidEncryptL(const TDesC8 &aInput,
TDes8 &aOutput
)const [virtual]

Encrypts the specified plaintext into ciphertext.

panic
KCryptoPanic If the input data is too long. See ECryptoPanicInputTooLarge
panic
KCryptoPanic If the supplied output descriptor is not large enough to store the result. See ECryptoPanicOutputDescriptorOverflow
ParameterDescription
aInputThe plaintext
aOutputOn return, the ciphertext

MaxInputLength ( void )

TInt MaxInputLength(void)const

MaxOutputLength ( void )

TInt MaxOutputLength(void)const

NewL ( const CRSAPublicKey & )

IMPORT_C CRSAPKCS1v15Encryptor *NewL(const CRSAPublicKey &aKey)[static]

Creates a new RSA encryptor object using PKCS#1 v1.5 padding.

leave
KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library. See TCrypto::IsAsymmetricWeakEnoughL()
leave
KErrKeySize If the key length is too small
ParameterDescription
aKeyThe RSA encryption key

Returns: A pointer to a new CRSAPKCS1v15Encryptor object

NewLC ( const CRSAPublicKey & )

IMPORT_C CRSAPKCS1v15Encryptor *NewLC(const CRSAPublicKey &aKey)[static]

Creates a new RSA encryptor object using PKCS#1 v1.5 padding.

The returned pointer is put onto the cleanup stack.

leave
KErrKeyNotWeakEnough If the key size is larger than that allowed by the cipher strength restrictions of the crypto library. See TCrypto::IsAsymmetricWeakEnoughL()
leave
KErrKeySize If the key length is too small
ParameterDescription
aKeyThe RSA encryption key

Returns: A pointer to a new CRSAPKCS1v15Encryptor object
