We are using Symantec PGP encryption for AIX to encrypt/decrypt files. Keys are generated with passphrase and the passphrase are set by the business users. The IT admin is responsible to perform the encryption/decryption of files on monthl… Continue reading PGP encryption passphrase
Basically looking for a replacement for PGP/GPG file encryption. Need “forward secrecy” feature.
I want to share encrypted files with someone else however it’s only for a short time only. What is the best way to do this?
More background: I’d like to add more people to be able to decrypt the file as time goes on and others “expire”… Continue reading Using GPG or PGP, is there a way to give another user (or key) access to decrypt a file for a limited time only?
We’re locally testing anasp.net application that will let a user upload documents. The app is similar to a jobs site like monster.com, but with sensitive data.
The app works great locally, and now we have to move it to a shared host or V… Continue reading Add security to documents uploaded?
I am using John the Ripper to crack a password hash for a school assignment and I am having some issues. John says that the password hash has been cracked but I cannot see what the actual password for the encrypted rar actually is when I… Continue reading John the Ripper is not showing what the acutal unhashed password is
I have a proposed method to encrypt files (I don’t know if it is actually applied or discussed).
The way I suggest is to use a sector to sector table in a random manner,
So if a specific sector of the file is x1 is mapped to y1 according… Continue reading File encryption based on directory table
Given a system that shares files for client-side decryption where the server does not know the encryption keys (just stores them in an encrypted form), is it – when sharing a file with a non-user – better to either
share the file encrypt… Continue reading Is it better to mask an encryption key or share it directly?
I am hunting for a solution where I can send someone encrypted files and a digital certificate that allows them to open the file.
The reason for doing it this way is because:
I don’t want to keep giving them a new password every-time I s… Continue reading Encrypting Files With A Certificate
The AES-GCM algorithm provides not only confidentiality but also integrity. I understand that integrity is an important part of security in overall, but whenever I think in terms of possible attacks, only attacks against encryption in tran… Continue reading Integrity attacks and encryption at rest
Many CLI applications store or need secrets in plaintext files.
I’m searching preferably for a tool, or a methodology, to encrypt those files without the application knowing.
What do I mean by that :
In my ideal dream world, when some pr… Continue reading Encrypt files transparently from applications
