Class SHA256CacheHash

Namespace

SixLabors.ImageSharp.Web.Caching

Assembly

SixLabors.ImageSharp.Web.dll

Creates hashed keys for the given inputs hashing them to string of length ranging from 2 to 64. Hashed keys are the result of the SHA256 computation of the input value for the given length. This ensures low collision rates with a shorter file name.
