I have been trying to pass a string encrypted with encrypt(3) through an INET socket to be decrypted on the other machine, but have been unable to do so. The same key is being used by both the client and the server, and the decrypted string differs from the original string by only a few letters. I have included all the code dealing with this problem. Will anyone tell me what i am doing wrong? Thanks. Jeff -------- client.c -------- char *pass; #ifdef SEND_PASS char *secpass; #endif . . . pass = malloc(64); pass = getpass("Password: "); . . . #ifdef SEND_PASS setkey(RPASSKEY); encrypt(pass, 0); secpass = malloc(strlen(pass)); strcat(secpass, pass); encrypt(secpass, 1); printf("%s", secpass); printf("%sbun\n", pass); strcat(buf, ":"); strncat(buf, pass, (strlen(pass) -1)); encrypt(pass, 1); printf("%s\n", pass); #endif -------- server.c -------- #ifdef SEND_PASS char *rch_secpass; #endif . . . #ifdef SEND_PASS char *bung, *block; block = malloc((strlen(rh->rch_secpass) + 1)); printf("%sbun\n", rh->rch_secpass); strcat(block, rh->rch_secpass); setkey(RPASSKEY); encrypt(block, 1); printf("%s:%s:%s:%s\n", rh->rch_mach, block, rh->rch_secpass, rh->rch_type); #endif --- -- marker@{troilus.math,balder.acc,dagon.acc,agnes.acc,thor.acc}.stolaf.edu martyr@dagon.acc.stolaf.edu markerj@carleton.edu I appreciate any comments on anything.
