|
<div><p>You can create DES and PKA keys and store them in a DES key store.</p>
|
|
<div class="p">You can use your Cryptographic Coprocessor to create two types of cryptographic
|
|
keys. <ul><li>Data Encryption Standard (DES) keys base their content on a symmetric
|
|
algorithm. This means that cryptography uses the same key value to encrypt
|
|
and decrypt data. Use DES keys to encrypting or decrypting files, working
|
|
with PINS, and managing keys. <p>To create DES keys with your Cryptographic
|
|
Coprocessor, write a program.</p>
|
|
</li>
|
|
<li>Public key algorithm (PKA) keys base their content on an asymmetric algorithm,
|
|
meaning that cryptography uses different keys for encryption and decryption.
|
|
Use PKA keys for signing files with digital signatures and for managing keys. <p>To
|
|
create PKA keys with your Cryptographic Coprocessor, write a program.</p>
|
|
</li>

</ul>

<div class="note"><span class="notetitle">Note:</span> If you choose to use the program examples provided, change them to suit
|
|
your specific needs. For security reasons, IBM<sup>®</sup> recommends that you individualize these
|
|
program examples rather than using the default values provided.</div>
|
|
<p>Store your DES and PKA keys in the key store file you created for them
|
|
using a key store file.You can also store PKA keys in your Cryptographic Coprocessor.
