This online tool allows you to generate the SHA256 hash of any string. SHA256 is designed by NSA, it's more reliable than SHA1. SHA256 hashed email lists are used for eg.
googleAds / AdWords Customer Match, Facebook-List-Custom-Audiences or Facebook Conversions API and Offline Conversions Matching Keys
Be sure that you have got the consent for processing PII! Even pseudonymous sha256 hashes maybe still PII... This free online sha256 hash generator tool does not need to be your processor, because you processing the data in your browser. Thus you are sha256 hashing by yourself to get eg. an email hash list for audience campaign or segments from your CRM data for facebook conversions API or other people based marketing activities.

This online generator is safe because the magic only happens in your browser and not on a server!

Try also the GDPR SHA256 + MD5-SALT Hash generator online for lists to pseudonymize (aka pseudonomize) PII.
Hopefully google and FB will enable this for their audiences, since with GDPR the single hash (this generator) may be rated unsave!
