Is sha1($s.md5($p)) possible to crack?

[digrolac]

I was wondering if it is possible to set this algorithm on Hashcat. I cannot seem to find a guide anywhere. Thanks.

Possible to crack? Yes. Does hashcat support it? No.

[digrolac]

Is there any workaround? Thank you for your quick response.

P.S the salt here is constant.

Hmm, well I suppose you could pre-hash your wordlist with MD5, then run it as -m 120, or -m 100 with -a 7.

Personally I'd probably just look into using dynamic formats in JTR.

Tried dynamics in JTR but it won't work.

Code:

[List.Generic:dynamic_1351]
Expression=sha1($s.md5($p))
Flag=MGF_INPUT_20_BYTE
Flag=MGF_SALTED
Flag=MGF_FLAT_BUFFERS
SaltLen=32
Func=DynamicFunc__clean_input_kwik
Func=DynamicFunc__clean_input2_kwik
Func=DynamicFunc__append_keys
Func=DynamicFunc__append_salt2
Func=DynamicFunc__SHA1_crypt_input1_append_input2
Func=DynamicFunc__SHA1_crypt_input2_to_output1_FINAL

HashManager at insidepro will let you do custom algorithm like that.
