Works great, except for ethereum

[weazelb0y]

Couldn't get -m 15700 (ethereum scrypt) working for me.

I have a hash of "Hi"

{"address":"6fea59d03567729c41545e9d6b22e970d03e0c6a","crypto":{"cipher":"aes-128-ctr","ciphertext":"04a4813a25457cc354d29a669c8d47893b642d3b999f2c89876d3756c23b0f6e","cipherparams":{"iv":"42781602a9a10147f572e935f8cecefc"},"kdf":"scrypt","kdfparams":{"dklen":32,"n":262144,"p":1,"r":8,"salt":"03b394784c4598d1b803661ddf6e7204cf1d85f99793cdbe8920964aaa5f3af5"},"mac":"9c1442d8f46951b6048fd3e8ca51ae82ae0b7f23d859f8a96c25e646d0ed56dd"},"id":"eb03b2a9-b5a0-4fd6-b855-e70469f2f9e4","version":3}

This is with Debian Sid's binary...

Code:

It seems like it never starts.

I also tried with latest from source.

Code:

❯ ./hashcat -d 1 -m 15700 -a 3 -1 '?u?a' -i --increment-min 1 --status ~/hi.json '?1?1' hashcat (v3.6.0-271-g942b7068) starting...

[s]tatus [p]ause [r]esume [b]ypass [c]heckpoint [q]uit => s [s]tatus [p]ause [r]esume [b]ypass [c]heckpoint [q]uit => s

This time when I press s, it doesn't say anything.

md5 works perfectly
hashcat -d 1 -m 0 -a 3 -1 '?u?a' --increment --increment-min 1 ~/md5 '?1?1'

Here is my opencl-info

Code:

❯ hashcat -D 1 --opencl-info hashcat (pull/1273/head) starting...

Let me know if there is anything I can try to help debug this.

Thanks!

SCRYPT is an anti-gpu algorithm, you can expect strange behavior especially with such high SCRYPT settings. Let it run for a few minutes or hours and do not interrupt. Or simply use a CPU device for "normal" behavior:
