| SecretKey | | final public class SecretKey implements Key(Code) | | Implements the base interface for keys used in symmetric algorithms.
|
| Constructor Summary | |
| public | SecretKey(byte[] key, int offset, int len, String algorithm)
Constructs a secret key from the given byte array, using the first len
bytes of key, starting at offset inclusive.
The bytes that constitute the secret key are those between key[offset]
and key[offset+len-1] inclusive.
This constructor does not check if the given bytes indeed specify a
secret key of the specified algorithm. |
| Method Summary | |
| public String | getAlgorithm()
Returns the name of the algorithm associated with this secret key. | | public byte[] | getEncoded()
Returns the key material of this secret key. | | public String | getFormat()
Returns the name of the encoding format for this secret key. |
| secret | | byte[] secret(Code) | | Local secret.

| SecretKey | | public SecretKey(byte[] key, int offset, int len, String algorithm)(Code) | | Constructs a secret key from the given byte array, using the first len
bytes of key, starting at offset inclusive.
The bytes that constitute the secret key are those between key[offset]
and key[offset+len-1] inclusive.
This constructor does not check if the given bytes indeed specify a
secret key of the specified algorithm. For example, if the algorithm
is DES, this constructor does not check if key is 8 bytes long, and
also does not check for weak or semi-weak keys. In order for those
checks to be performed, an algorithm-specific key specification class
must be used.
Parameters:
key - the key material of the secret key.
Parameters:
offset - the offset in key where the key material starts.
Parameters:
len - the length of the key material.
Parameters:
algorithm - the ID of the secret-key algorithm to be associatedwith the given key material. |

| getFormat | | public String getFormat()(Code) | | Returns the name of the encoding format for this secret key.
