# Xiaoyun

## Visual Elements


White t-shirt with a thin table with a variety of combinations of letters and numbers in it.

## Cultural Context

Wang Xiaoyun is a Chinese cryptographer famous for breaking the MD5 and SHA-1 hash functions in 2004-2005, work that fundamentally reshaped the field of cryptographic security. The table of letter-number combinations on this shirt represents the collision attacks she demonstrated against these widely-used hash algorithms.

<!-- justification
## Justification

Wang Xiaoyun broke two of the most important cryptographic hash functions in history. In a collection that honors the cypherpunk tradition, the woman who shattered SHA-1 deserves a shirt.
