Global file encryption means encrypting a group of files rather than a single file. The CRYP program can encrypt either single files (one file at a time) OR you can use the global feature of CRYP to encrypt a group of files meeting a certain file specification.
Examples of File Specifications:| Global File Spec. | Files to be encrypted globally |
|---|---|
| *.txt | encrypts all files having a .txt extension in the directory specified |
| *.exe | encrypts all files having an .exe extension in the directory specified |
| *.* | encrypts all files in the directory specified |
| a*.jpg | encryts all file names starting with the letter 'a' and having a .jpg file extension |
