Easy Hash
Quickly hash a file to share and compare without sacrificing your list

EasyHash doesn't save any of your data - everything is processed, hashed, and compared as a live stream of the file you upload and the results are returned to you only

Warning: md5 hashing is not a secure encryption method - do not use this tool to transfer any sensitive information such as passwords or payment data

Hash Single File

Hash your file to send an encrypted file to someone else

Upload File

Instructions

  • Upload your data (as .csv) from the mailer or CRM that you want to exchange (one column must be the column that you want to hash)
  • The dropdown for "Field to Hash" will automatically populate - select the field you want to hash
  • Download a file with only hashed data to send, and one with your original data and the hash

Compare Two Files

Compare your unencrypted file with someone else's hashed file

My File

Compare File

Instructions

  • Upload your data from the mailer or CRM that you want to exchange (one column must be the column that you want to hash)
  • The dropdown for "Field to Hash" will automatically populate - select the field you want to compare
  • Upload the pre-hashed file that you were sent and select the "Hashed Field" you want to use to compare
You will automatically download a zip folder with 3 files:
  • Your unique rows that don't overlap with the encrypted list (with full data)
  • The unique rows from the encryped list you are comparing to (with only hashes)
  • The overlap between the two files with hashes and data
