Line 78 of perturbations is selected. If

.Ar setting

begins with any other character, DES encryption with a fixed number

of perturbations is selected.

.Ss DES encryption:

.Ss "DES" encryption:

.Pp

The DES encryption scheme is derived from the

.Tn NBS

Data Encryption Standard.

Line 89 is a character array, 9 bytes in length,

Line 90 is a character array, 9 bytes in length,

followed by 4 bytes of iteration count and 4 bytes of salt.

Both the iteration

.Fa count

and the

.Fa salt

are encoded with 6 bits per character, least significant bits first.

The values 0 to 63 are encoded by the characters ``./0-9A-Za-z'',

Line 222 The

Line 223 The

specifies perturbations to

.Tn DES

as described above.

.Ss MD5 encryption:

.Ss "MD5" encryption:

.Pp

For the

.Tn MD5

encryption scheme, the version number (in this case ``1''),

.Fa salt

and the hashed password are separated

by the ``$'' character. A valid password looks like this:

.Pp

``$1$2qGr5PPQ$eT08WBFev3RPLNChixg0H.''.

.Pp

The entire password string is passed as

.Fa setting

for interpretation.
