2021-05-14: y_stringhash Hash Algorithm

You can change which hash function is used by y_stringhash:

• Bernstein (Default):
  
  

  
  switch (YHash(input))
  {
  ____case __H<hello>: {}
  ____case __H<world>: {}
  }
  

  
  
• Bernstein (Explicit):
  
  

  
  switch (YHash(input, .type = hash_bernstein))
  {
  ____case __H@b<hello>: {}
  ____case __H@b<world>: {}
  }
  

  
  
• FNV1:
  
  

  
  switch (YHash(input, .type = hash_fnv1))
  {
  ____case __H@f<hello>: {}
  ____case __H@f<world>: {}
  }
  

  
  
• FNV1a:
  
  

  
  switch (YHash(input, .type = hash_fnv1a))
  {
  ____case __H@a<hello>: {}
  ____case __H@a<world>: {}
  }
  

You would only need this in the extremely rare event that you get a hash collision between two cases. It is also important to note that these are NOT cryptographic hashes - they are use to compare simple string, NOT to store passwords.
