Hi, I want to encrypt and decrypt a string(database password) which will be used in my scripts.
encrypt the string while storing in a file and while using it in other scripts
it should decrypt.
i tried below method. As it can decrypt easily, it is not recommended.
Could you please suggest any other methods for this.
My Unix environment details are SunOS 5.10 Generic_118833-36
Thanks in advance.

Hi Everybody,
I have a script that telnet another system. For some reasons, this is should be done by "root", so the root password has been written explicitly in this script, which mean any body read this script will know the root password of the other system. I think the solution is to write... (6 Replies)

Dear Experts,
I am using one script name :volume.sh and its written in bash shell script.
I just want to encrypt the script so that any one else cannot see it.
please tell me the commands how to encrypt the script as well as to decrypt it.

Hello,
I wanted to know if there was a way to encrypt a string, not a file using openssl and then decrypt it? I cant seem to get it to work.

crypt
crypt(3) Library Functions Manual crypt(3)Name
crypt, crypt16, setkey, encrypt - DES encryption
Syntax
char *crypt(key, salt)
char *key, *salt;
char *crypt16(key, salt)
char *key, *salt;
void setkey(key)
char *key;
Description
The subroutine is the password encryption routine. It is based on the NBS Data Encryption Standard, with variations intended to frustrate
use of hardware implementations of the DES for key search.
The first argument to is normally a user's typed password. The second is a 2-character string chosen from the set [a-zA-Z0-9./]. The salt
string is used to perturb the DES algorithm in one of 4096 different ways, after which the password is used as the key to encrypt repeat-
edly a constant string. The returned value points to the encrypted password, in the same alphabet as the salt. The first two characters
are the salt itself.
The subroutine is identical to the function except that it will accept a password up to sixteen characters in length. It generates a longer
encrypted password for use with enhanced security features.
The other entries provide primitive access to the actual DES algorithm. The argument of is a character array of length 64 containing only
the characters with numerical value 0 and 1. If this string is divided into groups of 8, the low-order bit in each group is ignored, lead-
ing to a 56-bit key which is set into the machine.
The argument to the entry is likewise a character array of length 64 containing 0s and 1s. The argument array is modified in place to a
similar array representing the bits of the argument after having been subjected to the DES algorithm using the key set by If edflag is 0,
the argument is encrypted; if non-zero, it is decrypted.
Restrictions
The return values from and point to static data areas whose content is overwritten by each call.
Environment
Default Environment
In the default environment on systems that do not have the optional encryption software installed the function expects exactly one argu-
ment, the data to be encrypted. The edflag argument is not supplied and there is no way to decrypt data. If the optional encryption soft-
ware is installed the function behaves as it does in the POSIX environment. The syntax for the default environment follows:
void encrypt(block)
char *block;
POSIX Environment
In the POSIX environment the encrypt function always expects two arguments. The function will set errno to ENOSYS and return if edflag is
non-zero and the optional encryption software is not present. The syntax for the POSIX environment follows:
void encrypt(block, edflag)
char *block;
int edflag;
In all cases the function will set errno to ENOSYS and return if the optional encryption software is not present.
