Encrypt file (ENCRYPT)
The command ENCRPT is used to encrypt files. The i-effect *CRYPT functions encrypt files by using a PKI infrastructure, which results in an output file in the standard PK7 format. One tht one hand, this can be decrypted from any PKI system, and on the other hand, it presents a standardized way of displaying encrypted contents. To use this function, it is required that a public key exists in the recipient's i-effect keystore, and that the alias of the key entry is known. Furthermore, the i-effect modules *BASE and *CRYPT are required in order to use this command.
To reach the encryption menu, enter 12 from the i-effect menu and then menu item 4 "Encrypt Files".
The command ENCRPT and F4 can also be entered from the i-effect menu directly.
The following program interface will be displayed:
Description of the parameters:
| Keystore Alias (ALIAS) | The alias in i-effect's keystore, which will be used to encrypt the data of the input file. A public key (certificate) must be filed in the keystore under the alias. | ||||||
| Encryption Algorithm (ENCRYPT) | This parameter determines the type of encryption to be used for the specified input file.
| ||||||
| The Data Encryption Standard (DES) | is a widespread symmetric encryption algorithm with a key length of 3DES (=168 bits), which is three times as much as with DES encryption (=56 bits). The key's complexity is increased by a factor of 2^112. | ||||||
| Input Path (FRMPATH) | Determine the path in the IFS files system in which the files that are to be encrypted are stored. | ||||||
| Input File(s) (FRMIFSFILE) | Determine the PDF documents which are to be read from FRMPATH and then be used. By entering the wildcards "*" and "?" any number of files corresponding to the desired search pattern can be controlled.
| ||||||
| The following formats are possible for generic names: | |||||||
| ABC* | All files having the characters ABC at the beginning will be used, e.g. ABC, ABCD, ABCTEST. | ||||||
| a* | All files whose name is in quotation marks and begins with a will be used, e.g. "a," "aB," and "aD." | ||||||
| All files having the suffix ".pdf" will be used. | |||||||
| Output Path (TOPATH) | Determine the output path for the encrypted files. The file name corresponds to the original file name from the elements of the input path. In addition to the name, the suffix .pk7 will be added. If files with the same name already exist in the target directory, the original name will be kept and an add-on (number) will be inserted. | ||||||
| Rename File as (RENAME) | If it is desired that the encrypted files be renamed or given a new name or name pattern, this can be indicated here. With this parameter the standard settings for naming encrypted files can be changed.
| ||||||
| Name | A new name or name pattern can be entered here. The name pattern contains the wildcard "*" for the original file name IN FRONT OF the suffix and a second "*" for the suffix in the original file name.
