22 * This version of crypt has been developed from my MIT compatible DES
23 * library. Eric Young (eay@cryptsoft.com)
27 * Modification by Jens Kupferschmidt (Cu) I have included directive PARA for
28 * shared memory computers. I have included a directive LONGCRYPT to using
29 * this routine to cipher passwords with more then 8 bytes like HP-UX 10.x it
30 * used. The MAXPLEN definition is the maximum of length of password and can
31 * changed. I have defined 24.
34 #include <openssl/crypto.h>
38 * Added more values to handle illegal salt values the way normal crypt()
39 * implementations do. The patch was sent by Bjorn Gronvall <bg@sics.se>
