// Product: cv act library

|
|
// Purpose: The class Key manages information relevant to keys (e.g.
|
||
|
|
// domain parameters or the key itself). In the case of symmetric
|
||
|
|
// encryption only a (the) secret key is generated. In the case of
|
||
|
|
// of asymetric encryption a private and a public key are generated.
|
||
|
|
// This handle allows a universal approach for different families of
|
||
|
|
// algorithms.
