sorry, not possible. internal structures of both hashcat and oclHashcat can only work with a maximum password < 55 chars length.

Ah ok, anyway, thank you.
(By the way where this 55 comes from ? :p)
64 (password block buffer of sha1/md4/md5) - 8 (pw length) - 1 (0x80 stopbit)

If you are fine with a CPU implementation, ask on john-users (JtR mailing list) for it.

@atom: and how is WoltLab BB3 scheme exceeding this limit? Both the hash and the salt are 20 bytes in length (they are in hex). The maximum input length at a time is 40 bytes.

Are you sure about sha1($salt.sha1($salt.sha1($pass)))?
Code:

hash = binascii.unhexlify("e2063f7c629d852302d3020599376016ff340399")

m0.update(password)
m1 = hashlib.sha1()
m1.update(salt)
m1.update(m0.digest())
m2 = hashlib.sha1()

The output doesn't match the actual hash value using the encryption scheme you mentioned.
is that python snippet yours? If yes: who told you to use hexlify/unhexlify?
Code:
import hashlib

# WBB3 scheme -> sha1($salt.sha1($salt.sha1($pass))
hash = "e2063f7c629d852302d3020599376016ff340399"
salt = "0b053db07dc02bc6f6e24e00462f17e3c550afa9"
password = "123456"
m0 = hashlib.sha1()
m0.update(password)
m1 = hashlib.sha1()
m1.update(salt)
m1.update(binascii.hexlify(m0.digest()))
m2 = hashlib.sha1()
m2.update(salt)
m2.update(binascii.hexlify(m1.digest()))
print("Output:", binascii.hexlify(m2.digest()))
print("Actual", hash)

I did not know that it is using a hex encoded digest nor did I know its using a hex encoded salt string. In this case it would use 40 + 40 = 80 which is greater than 55.

Thanks for fixing it :-). It works now. I wrongly assumed that the given salt was to be un-hexed.

You were right. The maximum length is 80. The algorithm operates on hex encoded strings.
