Member Function Documentation

VirgilByteArray virgil::crypto::VirgilCipher::decryptWithKey ( const VirgilByteArray encryptedData,
const VirgilByteArray recipientId,
const VirgilByteArray privateKey,
const VirgilByteArray privateKeyPassword = VirgilByteArray() 
)

Decrypt given data for recipient defined by id and private key.

Note
Content info MUST be defined, if it was not embedded to the encrypted data.
See also
method setContentInfo().
Returns
Decrypted data.
VirgilByteArray virgil::crypto::VirgilCipher::decryptWithPassword ( const VirgilByteArray encryptedData,
const VirgilByteArray pwd 
)

Decrypt given data for recipient defined by password.

Note
Content info MUST be defined, if it was not embedded to the encrypted data.
See also
method setContentInfo().
Returns
Decrypted data.
VirgilByteArray virgil::crypto::VirgilCipher::encrypt ( const VirgilByteArray data,
bool  embedContentInfo = true 
)

Encrypt given data.

Parameters
data- data to be encrypted.
embedContentInfo- determines whether to embed content info the the encrypted data, or not.
Note
Store content info to use it for decription process, if embedContentInfo parameter is false.
See also
getContentInfo()
Returns
encrypted data.
