Duplicate of #1060

Not a duplicate - #1060 deals with length 92.

[jaimeMF]

Ok, sorry.
For me it's using length 92, maybe is just one of that strange lengths that Youtube gives sometimes.
I will try to reproduce

Dear @phihag @jaimeMF, there is no solution for signature length 90 yet? Thanks in advance for your hard work as always ;)

[jaimeMF]

I've added an algo for length 90.
Like in #1026: since there's no way to reproduce it, the fix may fail if you try to download the format that has this length. All the keys I've found are correctly decrypted. At least the extraction won't stop.

Type

sudo youtube-dl -U

to update to 2013.07.18, which contains support for 90 signatures.

[Baqan]

Thank for the fix. Good work!
