Public Constructors
public PKCS12ParametersGenerator (Digest digest)
Construct a PKCS 12 Parameters generator. This constructor will accept any digest which also implements ExtendedDigest.
Parameters
| digest | the digest to be used as the source of derived keys. |
|---|
Throws
| IllegalArgumentException | if an unknown digest is passed in. |
|---|
Public Methods
public CipherParameters generateDerivedMacParameters (int keySize)
Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with.
Parameters
| keySize | the size of the key we want (in bits) |
|---|
Returns
- a KeyParameter object.
public CipherParameters generateDerivedParameters (int keySize)
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with.
Parameters
| keySize | the size of the key we want (in bits) |
|---|
Returns
- a KeyParameter object.
public CipherParameters generateDerivedParameters (int keySize, int ivSize)
Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with.
Parameters
| keySize | the size of the key we want (in bits) |
|---|---|
| ivSize | the size of the iv we want (in bits) |
Returns
- a ParametersWithIV object.
