1. Where & How Configurations Saved

Although not as important as 2. below, it’s good to know

  what DoCrypt –or any program– does with your choices.

All of your configuration files are in folder

PROP_DIR

It's the same place as docrypt.jar

JAR_PATH

All DoCrypt saved program data is under this folder.

( click displays current configuration. )

pages 59-62: Integrity

How cryptographic fingerprints work

Hands-on cryptographic fingerprints

· Verify your copy of DoCrypt against our published fingerprint

(Click File radio button to fingerprint our program doCrypt.jar.

Matching it against our website's fingerprint verifies its integrity.)

· Using fingerprints at end of DES–AES Messages

Shows the constancy of crypto fingerprints.

FingerPrint a Group-of-Files Example

Launching fingerPrinter here will do (1) and (2) below

for CURRENT_CONFIG (the current configuration)

Another Strong Argument for FingerPrints

You might, reasonably, think encrypted text can't changed

so it decrypts to meaningful text. Not so. See this
