+Euler's Theorem, a cornerstone of [Number Theory](/wiki/Number_Theory), establishes a powerful congruence relation. It states that for any two [Coprime](/wiki/Coprime) integers, one raised to the power of Euler's totient of the other is congruent to one modulo the other. This elegant theorem generalizes [Fermat's Little Theorem](/wiki/Fermat's_Little_Theorem) and is crucial in modern cryptography.
