Double Salted Hash - SHA1 and SHA256

[William]

Howdy,

I've come across what I'm told is a double salted hash that is either SHA1 or SHA256

I have this hash that I'm wondering if there is a way to identify which one it may be and if hashcat-gui given an infinite amount of time is able to crack?

The hash looks like this b4cd077a3c69e175a9063a57fad32df8883737da

sha1(sha1(password) . salt)

or

sha256(sha256(password) . salt)

Any information on this is appreciated. I'm a bit new but all I can see in the list of hash types in hashcat-gui that comes remotely close to this is sha1(sha1($pass))
