SHA-3

JavaScript Obfuscator

ASCII

AES

To produce a fixed-length string from arbitrary input

To make source code harder to replicate

To transform data into another format using a public scheme

To securely send a password over the Internet

It produces a fixed-length string

It detects modifications via changes to the hash output

It can be reversed to obtain the original input

The same input always produces the same output

It always produces a fixed-length output

It requires a secret key

The result must still be consumable by the computer
