Steps for decoding data
To decode data:
- Select option 5, UTILITY, on the Primary Option panel and press
ENTER.
The Utilities panel appears. See Figure 1.
Figure 1. Selecting the Decode Option on the Utilities Panel CSFUTL00 ---------------- ICSF - Utilities -------------------------- OPTION ===> 2 Enter the number of the desired option. 1 ENCODE - Encode data 2 DECODE - Decode data 3 RANDOM - Generate a random number 4 CHECKSUM - Generate a checksum and verification patterns 5 CKDSKEYS - Manage keys in the CKDS 6 PKDSKEYS - Manage keys in the PKDS 7 PKCS11 TOKEN - Manage PKCS11 tokens in the TKDS Press ENTER to go to the selected option. Press END to exit to the previous menu. - Select option 2, Decode, on this panel.
The Decode panel appears. See Figure 2.
Figure 2. Decode Panel CSFECO00 -------------- ICSF - Decode ------------------------------ COMMAND ===> Enter data below: Clear Key ===> 0000000000000000 Clear Key Value Ciphertext ===> 0000000000000000 Data to be decoded Plaintext : 0000000000000000 Output from the decode - In the Clear Key field, enter the clear value of the key you want ICSF to use to decode the data. This needs to be the same key value that was used to encode the data.
- In the Ciphertext field, enter the data in hexadecimal form that you want ICSF to decode.
- Press ENTER.
ICSF uses the clear key and the DES algorithm to decode the data. The decoded data is displayed in the Plaintext field.
- Press END to return to the Utilities panel.
- Press END to return to the Primary Option panel.
