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...

This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.

It seems like it never starts.

I also tried with latest from source.

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'

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:
