The video states that modular arithmetic is a central mathematical concept in cryptography and that widely used cryptographic algorithms mainly depend on it.
Conditions: This is a motivational claim stated by the video.; No specific algorithm is named in this segment.

Modular arithmetic is a system of arithmetic for integers in which values wrap around after reaching a certain value called the modulus. The video introduces this concept as central to cryptography.
Conditions: Applies to integers.; A modulus value is needed to define the wrap-around behavior.

The clock example illustrates wrap-around by showing that although a day has 24 hours, a 12-hour clock uses only 12 numbers. Times beyond 12 map back onto the same cycle, such as 15 hours becoming 3 p.m.
Conditions: The example uses a standard 12-hour analog clock.; The modulus is 12.
