Applying salt in email marketing involves several steps:
Generating Unique Salt: For each email address or password, generate a unique, random string of characters (salt). Combining Salt with Data: Append or prepend the salt to the email address or password before hashing. Hashing the Combined Data: Use a secure hashing algorithm, such as SHA-256 or bcrypt, to hash the combined salt and email address/password. Storing Salt and Hashed Data: Store the salt and the hashed value in the database. The salt is stored in plain text, while the hashed value is stored securely.
