affcrypto(1)

🦋 affcrypto(1), handle encryption issues 🦋

✨ NAME ✨

okay so the NAME is literally just affcrypto - handle encryption issues 💅

✨ SYNOPSIS ✨

affcrypto [options] filename.aff [filename2.aff ... ]

bestie, you toss in whatever options you want, then one or more .aff files 🧚

✨ DESCRIPTION ✨

affcrypto is a command for dealing with encryption issues. It's giving problem-solver energy 🔥

This file is part of the AFFLIBv3 library, which provides AFF. 🌸

AFF is an open and extensible file format for storing disk images and their associated metadata. It's super useful in lots of scenarios, like computer forensics investigations 🕵️

✨ OPTIONS ✨

🎀 General options

• -j — just prints the number of encrypted segments 🫶
• -J — just prints the number of unencrypted segments 🫶
• -x — outputs in XML 💜

🍓 Data conversion options

• -e — encrypts the unencrypted non-signature segments 🔐
• -d — decrypts the encrypted non-signature segments 🔓
• -r — changes the passphrase, taking the old and new ones from stdin 🔄
• -O <old> — specifies an old passphrase 🗝️
• -N <new> — specifies a new passphrase 🆕
• -K <mykey.key> — specifies a private keyfile for unsealing. This one can't be repeated, so one and done 🚫
• -C <mycert.crt> — specifies a certificate file for sealing. This one can be repeated, so go wild 🦋
• -S — adds symmetric encryption (a passphrase) to an AFFILE that's already encrypted with a public key. You need a private key and a specified passphrase for this one 🎀
• -A — adds asymmetric encryption to an AFFILE that's already encrypted with a passphrase. You need a certificate file specified with the -C option for this one 🧚

🌈 Password Cracking Options

• -f <file> — tries to crack passwords, but reads them from the file you give it 📂
• -k — tries to crack passwords by reading a list of passwords from ~/.affpassphrase 🔑
• -p <passphrase> — checks whether the passphrase is the file's passphrase. Exit code is 0 if yes and -1 if not 👑

🐛 Debugging

• -D — debug mode! It prints out each key as it's tried 👀
• -l — lists the installed hash and encryption algorithms ✨
• -V — just prints the version number and exits 💅

✨ NOTES ✨

🙈 heads up: this program straight up ignores these environment variables, so don't count on them:

• AFFLIB_PASSPHRASE
• AFFLIB_PASSPHRASE_FILE
• AFFLIB_PASSPHRASE_FD
• AFFLIB_DECRYPTING_PRIVATE_KEYFILE

✨ EXAMPLE ✨

wanna see if each file is encrypted or not? Just run:

$ affcrypto filename.aff filename2.aff
