HMAC-SHA1 mask

[kuroro]

I'm currently trying to make HMAC-SHA1 cracking work with hashcat. To make thing easier, I precomputed a digest with a known "message" and "secret".

Code:

$ echo -n "The quick brown fox jumps over the lazy dog" | openssl dgst -sha1 -hmac "key"
de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9

Basically, we know that:

secret: "key"
message: "The quick brown fox jumps over the lazy dog"
digest: de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9

Now, I want to test hashcat by cracking the secret using the mask attack mode given the digest and message.

Using the command below, hashcat wasn't able to find the key. What am I doing wrong?

Code:

$ ./cudaHashcat64.exe -m 150 -a 3 --increment --increment-min=3 --increment-max=3 de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9:"The quick brown fox jumps over the lazy dog" ?l?l?l

ATTENTION!
The wordlist or mask you are using is too small.
Therefore, oclHashcat is unable to utilize the full parallelization power of your GPU(s).
The cracking speed will drop.
