Web3.js: Web3js 1.0 has issue in decrypting some UTC file.

[anurag-lala]

Previously the format of UTC file was:-
{"version":3,"id":"09ddd0cf-76ed-4254-8912-adedb549fbcb","address":"e97a49f8e62767dad8d61c2e951eafb28a0adb37","Crypto":{"ciphertext":"b887c29ba299793af2ec9535fe6934b04ae34cbc1b745396eaea3ac931b593dd","cipherparams":{"iv":"7dfd0a849313c0e84e302b527c343499"},"cipher":"aes-128-ctr","kdf":"scrypt","kdfparams":{"dklen":32,"salt":"ad883dc67f42508c56e467969d58d8abac3ab5360c61e515a80bddff6dfcf964","n":1024,"r":8,"p":1},"mac":"6d1d8c50fcb1498e38479498169b3692f018e96f40aa4d972bd6578b761a1d30"}}

And when we use web3.account.encrypt it generated like this

{"version":3,"id":"09ddd0cf-76ed-4254-8912-adedb549fbcb","address":"e97a49f8e62767dad8d61c2e951eafb28a0adb37","crypto":{"ciphertext":"b887c29ba299793af2ec9535fe6934b04ae34cbc1b745396eaea3ac931b593dd","cipherparams":{"iv":"7dfd0a849313c0e84e302b527c343499"},"cipher":"aes-128-ctr","kdf":"scrypt","kdfparams":{"dklen":32,"salt":"ad883dc67f42508c56e467969d58d8abac3ab5360c61e515a80bddff6dfcf964","n":1024,"r":8,"p":1},"mac":"6d1d8c50fcb1498e38479498169b3692f018e96f40aa4d972bd6578b761a1d30"}}

So while decrypting only second one will work (web3.account.decrypt). This is just because of Crypto in UTC file.

I encountered the issue.
ALSO it should be an async function, it takes 5 to 10 seconds to decrypt

@anurag-lala I was going back in the commit history and the crypto property was always written lower case in 1.0. I will close this issue because there isn't something I have to fix but feel free to ping me here again and we can discuss further steps.

@alexbourdon Yes, you are right it should be an async function. I've written this down on my todo list and will change this probably on the 1.3.0 release.
