When doing engineering designs, we are assuming...

Factoring Problem

• Assumption: It's hard to factorize a large integer to two primes.
• Or: RSA will be done.
• Mitigation: Post-quantom algorithms.

Hashing algorithms like MD5/SHA-1

• Assumption: MD5/SHA-1 of two pieces of different data are different.
• Or: Potential of impersonation. (Check SHAttered.io.)
• Mitigation: SHA-256 seems to be still okay.

UUID

• Assumption: Generated UUIDs will not collapse.
• Or: Collision leads to confusion.
• Mitigation: Twitter's Snowflake.
