As you know, RC4 is a stream chiper which is used in WEP.
RC4 needs 2 inputs (key, plain text) to generate the keystream, right RC4 key is rk+iv. So what is plain text to encrypt?
Does RC4 use rk+iv to encrypt rk?
Is rk plain text?
What is rc4 encryption key than rc4 uses it to encrypt rk+iv ?
I am trying to decrypt a password protected xls file. Currently I was able to extract the hash file. The hash file I have extracted is encrypted with $0/$1, MD5 + RC4, collider #1 hashing algorithm and I thought that Hashcat is the suitabl… Continue reading Hashcat mask attack password length restriction [closed]
I need to open an excel file and see its contents which is locked with password. As I made some research on the internet, I have found that only way was a brute force attack. So I used John the Ripper on Ubuntu, and detected and extracted … Continue reading Decrypting xls file using John The Ripper
Running this command resulted with the list of ciphers which supports rc4:
/usr/bin/openssl ciphers -v | grep -i "rc4"
What’s the easiest way and how to remove specifically ciphers that supports rc4 that I need to execute or whe… Continue reading Way to remove rc4 from Linux Cipher Suites
Good Day,
The following article: https://research.checkpoint.com/2020/phorpiex-arsenal-part-i/
mentions the structure of a payload for Phorpiex malware.
I am trying to decrypt such file, and to my understanding it should be possible s… Continue reading RC4 Malware Payload decryption with Python
So I understand that a keystream is generating from a key and is the length of the message you want to send, so that you can properly XOR every bit. But I’m having trouble finding and understanding the algorithm for creating the keystream … Continue reading How to generate the Keystream from IV+Key in RC4
I’ve found that UltraVNC Single Click is an interesting alternative to TeamViewer.
However it as far I understand uses RC4 to encrypt. Would you recommend this tool to remote desktop bearing in mind the security?
I know that WEP has been replaced by TKIP. TKIP still uses RC4, but in it the Initialization Vector (IV) is longer and it’s used with the MAC of the sender and a hardcoded WEP key to generate the key used in RC4. I also read … Continue reading Algorithm that change keys in TKIP
I’m running an Apache 2 server with Ubuntu 16. Here’s my current configuration:

I’m a bit confused as to what I should use for SSLCipherSuite. I’m takin… Continue reading SSL – Enabling Forward Secrecy with or without RC4
