No, one of the advantages of MegaCryption is that not all external partners are required to purchase a license. The product itself consists only of 2 libraries and occupies 80 tracks on a 3380 disk. Approximately the same as the full version of the product. And of course, it depends on the MIPS available. The customer should do some tests on its own machine to get an idea of the CPU time required.
Decryption takes about the same CPU as encryption.
Encryption keys must be available to decrypt a file. MegaCryption recovers in the same manner as most other solutions. No, MegaCryption is compatible with many PC encryption products. The Random Keys that are generated with MegaCryption encrypted files are generated using the processor clock and passing the result through the DES algorithm.
