Here's a taste of the code. Open the full example in WebVB Studio to explore, modify, and run it.

Visual Basic 6

Sub cmdEncrypt_Click
    Dim key As String
    key = txtKey.Text
    Dim encrypted As String
    encrypted = Encrypt(txtInput.Text, key)
    txtOutput.Text = encrypted
End Sub

Sub cmdDecrypt_Click
    Dim key As String
    key = txtKey.Text
    Dim decrypted As String
    decrypted = Decrypt(txtInput.Text, key)
    txtOutput.Text = decrypted
End Sub

Sub cmdHash_Click
    txtOutput.Text = Hash(txtInput.Text, "SHA-256")
End Sub

Python

def cmdEncrypt_Click():
    encrypted = Encrypt(txtInput.Text, txtKey.Text)
    txtOutput.Text = encrypted

def cmdDecrypt_Click():
    decrypted = Decrypt(txtInput.Text, txtKey.Text)
    txtOutput.Text = decrypted

def cmdHash_Click():
    txtOutput.Text = Hash(txtInput.Text, "SHA-256")
