Let H = H(PK). - 2. Let H' = the first 130 bits of H, considering each octet from + 2. Let H' = the first 80 bits of H, considering each octet from most significant bit to least significant big. 2. Generate a 26-character encoding of H', taking H' 5 bits at a time, and mapping each 5-bit value to a character as follows: 0..25 map to the characters 'a'...'z', respectively. 26..31 map to the characters '0'...'5', respectively. - (We only use 130 bits instead of the 160 bits from SHA1 because we don't - need to worry about man-in-the-middle attacks.
