Hash Encode Password Generator

Hash Encode Password Generator

A library that generates keys using hashing and encoding.

The difference with other password generators is that you use a simple word to generate complex passwords.

Setting your pet name as a password is not secure. But having a method generating a complex password out of it, can be.

How it works

The process works as follows:

• You have a predefined string which you know and will contain your password eg "My Dog's name is {input}"
• You replace input with your pet name eg "simba". That makes the string "My Dog's name is simba"
• This string is now goes through hashing with a chosen algorithm (MD5, SHA256, SHA512)
• The hashed string now is encoded in a chosen format (hex, base32, base64, base85)

Complexity support

Time constraints

In the formatted string, some date functions are supported to make encode time in it, so that you can create an expiration effect if used in the server:

• Y : current year
• M : current year and month
• D : current year month and day
• H : current year month day and hour
• W : current year and week in year
• Q : current year and quarter of year

PI digits

If you want to have a complex string without remebering it, the PI function will add the PI digits between the range of (pi-from to pi-to). That means if you add {PI} in your formatted string and declare pi-from=321 pi-to =1231, it will insert the digits between these positions. (It starts from position 0 being the 3 in 3.14)

Examples

hepg -t "Hello {input}" -i "World" -a sha256 -e base64

Output:

hepg -t "Hello {input}" -i "World" -a sha256 -e hex

Output:

hepg -t "Hello {input}" -i "World" -a sha512 -e base85
