decrypting SaveData gives this error: header signature is invalid!

[alpakeno]

Tried 2 savedata and both gives this error, here is the log:

psvpfsparser.exe -i PCSE00899 -o PCSE00899_dec -z "KO5ifR1dQ+eHBhgYmptDTbWwtATZ7+/i6Rcc4OEa5OoDssoAn//cAvu/cR6foneAh0NIVGRmymiMD24AAMciEoQA" -f http://cma.henkaku.xyz

psvpfsparser.exe -i PCSA00008 -o PCSA00008_dec -k 5269EBF7649358B87AB9A045EC1DDF5D -z KO5ifR1dQ+eHBlgi6TKwANkf5BrsGRzi6OfsGuYZ4hgajM9/QZmvv6dMjthRtXOB6xvZ+7GDPDqYR3p6BAD7VhY9 -f http://cma.henkaku.xyz

I should have added this to readme.
You dont use zRIF string or klicensee for decrypting savedata or trophies.
Dont provide any of those arguments. Key is taken from sealedkey file.

thanks for the info, that's works :)

now i get this error when trying to decrypt save file from from mai dump for this game "PCSE00899"
All mai dump saves gives this error "keystone: invalid magic" but still decrypt it to the output folder except "PCSE00899" it give "Unexpected padding" error, here is the log:

@alpakeno
I can only say to you that mai dump stuff is not canonical.
Maybe some crap is written to savedata and this is related to using mai?
You could try sharing this file. I will try to check, but most likely smth is wrong with the savedata.

[alpakeno]

I thought that it's related to mai issue for this game "PCSE00899" to not be able to decrypt it...
But after trying to decrypt SaveData for the physical version of this game "PCSE00019" it gives the same warning and error "Unexpected padding", so i think it's related to parsing the icv.db...
Unfortunately, in the mean time i cannot provide the SaveData file because it's not mine.

@alpakeno
Ok, thats interesting. If this is not related to mai - I will try to add some code that ignores this padding and writes only warning.

[alpakeno]

Thanks, that's will be nice.
