Probably different character maps? Did you write the encryption algorithm yourself or do you rely on some sort of library? If the latter is the case maybe the algorithms are different or just use a different "seed" to come to different results.
A good encryption algorithm gives to different results even with the same input - this way you have no way to get the input from the result without knowing the algorithm and knowing the secret information. An algorithm which gives, for instance, a "B" for every "A" is more likely to be compromised than one which gives a "B" first and a "C" for the next pass and an "X" for the next aso..
I hope this helps.

get_crypt_name
get_num_crypts(3) Library Functions Manual get_num_crypts(3)
NAME
get_num_crypts, get_crypt_name - determine the encryption types available (Enhanced Security)
LIBRARY
Security Library (libsecurity.so)
SYNOPSIS
#include <prot.h>
int get_num_crypts(void);
const char *get_crypt_name(
int cryptnum);
PARAMETERS
cryptnum
The encryption algorithm for which the name is to be returned.
DESCRIPTION
The get_num_crypts() function returns the number of encryption algorithms which the current system supports. This value is non-negative,
and at least four.
The get_crypt_name() function returns a pointer to static storage containing the name of the encryption algorithm with the index value
given in the cryptnum parameter. Other calls to get_crypt_name() could overwrite the stored name, so applications should copy the names
this function returns if there is a chance that other parts of the application might also call this function. This function returns NULL
if the given algorithm index is negative or if it is not less than the return value of get_num_crypts(). Algorithm indexes are most com-
monly obtained from the fd_oldcrypt and fd_newcrypt fields of an extended profile entry.
The dxaccounts system management GUI uses the get_num_crypts() and get_crypt_name() functions to determine how to display the menu of
allowable encryption algorithms for ENHANCED security.
RETURN VALUES
The get_num_crypts() function returns a non-negative value which is at least four.
The get_crypt_name() function returns a name for a known encryption algorithm, or a NULL pointer if the given index is out of range.
NOTES
In order to quickstart a program, the program must be linked as follows:
-lsecurity -ldb -laud -lm
See the shared library discussion in the Programmer's Guide for more information about using the quickstarting feature.
