This is probably the common question on stack exchange but I need to know is this really safe as it seems to be?
//Password hashing stage 1
$a_password = sha1($a_password);
$a_password = md5($a_password);
$a_password… Continue reading How secure is my hashing algorithm?

I have a couple of things I would like to explore with hashcat. I have a MD5 hashed password, which I know for a fact has a prefix and a suffix. The actual password is located in the middle of the prefix and the suffix, and t… Continue reading Brute force MD5 with a prefix and suffix up to n characters/words
For my work I’ll need to provide my customer a specific file which will be the result of the work I have done for them.
To protect the integrity of the work I have done and to guarantee it has never been modified, I intend to add a checksu… Continue reading Which hashing algorithm shoud I use for a safe file checksum?
I’ve been storing files using a filename of the md5 hash of the file. This allows me to not store duplicates of the same file and avoids any filename clashes. Each file has uses a different salt/iv.
I want to start encryptin… Continue reading Potential security issue with md5 filename
Recently Twitter published a csv file containing info about the account that were spreading governments-supported propaganda:

I am trying to make a folder encryption with maximum automation (except password input).
Inside a bash script I do the following:
echo $RANDOM | md5sum | cut -d’ ‘ -f1 > iv
and then using it:
openssl aes-128-cbc -m… Continue reading The way to determine IV for AES encryption, possible security problems with this approach
There’s some old data encrypted with OpenSSL 1.0.2, but now OpenSSL is at 1.1.0. I understand from OpenSSL FAQ USER3 that an old file can be decrypted with 1.1.0 by using -md md5. But let’s say you had newly encrypted files too? Then so… Continue reading Is it possible to tell if a file’s message digest is MD5 or SHA-256?
I’m a developer and suddenly I fall in a stupid situation like I need to crack a hash Joomla password which is (5aa154999c111bf7f33a1a3cadba5847) and I don’t know the salt. is there any way to crack this hash password?

We are in the process of choosing a hashing algorithm for file verification. As some of our files are large (up to 1 GB), performance of the algorithm is a high priority. Initial testing of certain algorithms from fastest to … Continue reading Security of weak hashing algorithms if message size is fixed
