Generate A Triple Des Key Coded In Base64
Anas: openssl rand. 24 generates a 192-bit key, which if encoded in base64 is 32 chars (plus a system-dependent line terminator). 192-bits is the correct size for the key of what OpenSSL calls des-ede3 (officially TDEA keying option 1); 128-bits would be correct for OpenSSL's des-ede (which is TDEA keying option 2).
- Encrypt a file using triple DES in CBC mode using a prompted password: openssl des3 -salt -in file.txt -out file.des3 Decrypt a file using a supplied password: openssl des3 -d -salt -in file.des3 -out file.txt -k mypassword Encrypt a file then base64 encode it (so it can be sent via mail for example) using Blowfish in CBC mode.
- You may also be interested in looking at the following, related Code Project articles: Generic SymmetricAlgorithm Helper This is a generic helper class that exposes simplified Encrypt and Decrypt functionality for strings, byte arrays and streams for any SymmetricAlgorithm derivative (DES, RC2, Rijndael, TripleDES, etc.).
- I am working with OpenSSL using Windows 10 CMD. I am trying to encrypt something using triple des with key coded in base64 that stored in text file (assume that plain text is:'hi all I am someone', key.txt (key 24 byte coded in base64)), so I wrote this command line: openssl enc -des-ede3 -pbkdf2 -base64 -in input.txt -out output.txt -k key.txt.
- Useful, free online tool that decrypts Triple DES-encrypted text and strings. No ads, nonsense or garbage, just a DES decrypter. Press button, get result.
- Symmetric Ciphers Online allows you to encrypt or decrypt arbitrary message using several well known symmetric encryption algorithms such as AES, 3DES, or BLOWFISH. Symmetric ciphers use the same (or very similar from the algorithmic point of view) keys for both encryption and decryption of a message.
Generate A Triple Des Key Encoded In Base64
Background:
My application reads an encrpyted-base64 password from a config file and
decrypts the same inside the application. The password is encryped using
Triple-DES algorithm.
To encrypt and base64 the actual password, a stand-alone utility is
provided. We run this utility, and then copy-paste the generated password in
the config file. Of course, the key, the IV (Salt not used) are same
(hard-coded) in both the applications.
So far, so good.
Now, we have to make the keys available in another file (Which will be kept
under more security). Both the applications are to read the key from the
file. Now, we have to generate the key and then write out the key in the
file.
Question:
So, the question is: How can we generate a key for Triple DES encryption and
write out the same in a file?
I tried the genrsa and dsa options but they seem to generate keys for
RSA/DSA encryptions. Also, we can specify the length of modulus in those
keys. But they will not map well in T-Des case.
Any pointers would be welcome.
Thanks.
