I will presume that Alia needed a masturbation break.  For this class in applied cryptography, that is called “homework”.

Funny because that's actually what I just did

Good girl.  I hope you got good avalanche effect.  (Will explain what that means...)

Consider a hash function, such as the SHA-256 algorithm used by Bitcoin in many places.  Among other properties, a cryptographically secure hash has the property that for any 1-bit change in the input, on average, 50% of the output bits flip.  See how this works:

Code:
user@host:~$ echo -n 'b' | sha256sum
3e23e8160039594a33894f6564e1b1348bbd7a0088d42c4acb73eeaed59c009d  -
user@host:~$ echo -n 'c' | sha256sum
2e7d2c03a9507ae265ecf5b5356885a53393a2029d241394997265a1a25aefc6  -

I have here chosen 'b' and 'c' for the sake of example, because ASCII 'b' (0x62) is one bit different than 'c' (0x63).  ('a' (0x61) and 'b' (0x62) differ in 2 bits.  Well, that’s another lesson.)

Thus, as you felt the caress of my words and imagined my cock in your hot, wet cipher, every 1-bit of thrust between us should have made you feel half-scrambled with ecstasy.

Was that explanation sufficiently clear, or do I need to somehow involve a spanking?  I know you like that; and I may need to apply such measures, if you fall behind in this lesson.
