Please submit a Python code that can encrypt and decrypt any English message using the key "CIPHER". The encryption algorithm should shift the letters in the plaintext as much as the corresponding letter in the key. For example: PlainText: TEST Key: CIPHER Encrypted Text: WNIB T+C=WE+I=NS+P=IT+H=B PlainText: THIS IS A TEST Key: CIPHERCIPHERCIPHER.... Encrypted Text: ..... T+C H+I I+P S+H I+E S+R
