Hello, I can't decrypt arc4. I tried two versions of decryption script with almost the same tips. How can I solve this problem?

Same here, were you able to fix this?

[yanncam]

From your UnSHc execution shown behind, you have tried to run UnSHc on a file a.sh and not a.sh.x.

Try again with the right enrcrypted file.

I had the same arc4() error with
i.sh.x: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=f6faf4df13eeaf8681bce8c1a5c29d90aa5865, stripped

Hello,

Which version of shc do you use ?
UnSHc need the *.sh.x file as argument, not the *.sh.
Please read : #31

Sincerely,
