I have a file which is encrypted using AES 128 and I have a key file whose size is 48 bytes. How can I decrypt the file using the key file?
The key file has no extension, I opened it in notepad and it has bizarre text.
I have IV as 0x496daa1c6914000e408c65cead91fc29
.
I don't know the cipher used for encryption but my guess is 80% for CBC.
Edit: More Info-> I am trying to decrypt an HLS stream, the m3u8
file has this line
#EXT-X-KEY:METHOD=AES-128,URI="k/timestamp",IV=0x496daa1c6914000e408c65cead91fc29
which indicates that the file named "timestamp" is the key file, but its size is 48 bytes.
I am using Windows 10 but can switch over to Linux.
I don't know the OS used for encryption and the thing(OpenSSL,enc) that is used for encryption.
I am completely new to encryption and decryption.
