mcell.dir file settings that control encryption

The mcell.dir file contains a field for an EncryptionKey. At installation, the default EncryptionKey value is set to mc. BMC recommends that you modify the value for security.

The string specified as the encryption key is transformed to a binary value as follows:

• Characters of the encryption key are grouped in pairs. If the string has an odd number of characters, the last character is ignored. 
• Each pair is converted to an 8-bit value. The first character of the pair determines the four most significant bits, the second character determines the four least significant bits. 
• A character in the hexadecimal range (0 – 9, A – F, a – f) is converted to the corresponding hexadecimal value (for example, 8 gives the value 8, B gives the value 11).
• Any other character is converted to its ASCII code modulo 16.
