react-native-crypto freezes android app for ~10sec when signing content -


i'm using react-native-jwt generate jwt google pubsub. library uses react-native-crypto inside signing data.

that works great in debug mode (when calculations performed in packager), leads app freeze in release mode on android device.

here line causes freeze:

crypto.createsign(method).update(input).sign(key, 'base64');

where crypto react-native-crypto , method rsa-sha256.

any thoughts cause of problem?

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
