BIP38 Encrypt show password in plaintext

[Tri125]

Just a small suggestion to improve the security a bit. To prevent prying eyes (or screen recording software) from seeing the password, it would be best to

• Remove the paperencryptpassphrase div.
• Set the paperpassphrase input type to password
• Add another input to confirm the passphrase to avoid the user making a typing mistake.

On the plus side, by using a password input if someone makes a non-HTTPS rehost of the website, the end user will be warned by their web browser that it is not secured.
