Section 5.13. says:
The plaintext of the data to be encrypted is passed through the SHA-1 hash function, and the result of the hash is appended to the plaintext in a Modification Detection Code packet. The input to the hash function includes the prefix data described above; it includes all of the plaintext, and then also includes two octets of values 0xD3, 0x14. These represent the encoding of a Modification Detection Code packet tag and length field of 20 octets.
It should say:
The concatination of the prefix data descibed above, the plaintext to be encrypted and two octets of values 0xD3, 0x14 (These represent the encoding of a Modification Detection Code packet tag and length field of 20 octets) is passed through the SHA-1 hash function.
Notes:
The text is misleading and contradicting.
