Getting Started with Data Hasher

Data Hasher lets you generate secure, one-way hashes of CRM property values directly inside your HubSpot workflows. Use it to anonymize sensitive data, create unique identifiers from multiple fields, detect duplicate records, or verify data integrity - all without writing code or leaving HubSpot.

How It Works

1. A HubSpot workflow reaches the Hash Data action for a contact, company, deal, or ticket
2. You choose which property to hash, pick an algorithm (SHA-256, SHA-512, MD5, bcrypt, or Argon2id), and optionally combine a second property value
3. The app generates a one-way hash and returns it as an output you can use in later workflow steps
4. Your workflow branches based on whether the hashing succeeded, and you can copy the result into any CRM property for future reference

Key Capabilities

Multiple Hashing Algorithms

Choose the algorithm that fits your use case:

• SHA-256 - the recommended default for most scenarios: deduplication keys, fingerprinting, data anonymization
• SHA-512 - a longer hash for situations requiring higher collision resistance
• MD5 - available for legacy system compatibility (not recommended for security purposes)
• bcrypt - industry-standard password hashing with built-in salting
• Argon2id - the most secure option for credential storage, resistant to GPU-based attacks

Multi-Field Hashing

Combine two property values into a single hash. For example, hash an email address together with a company domain to create a unique record fingerprint. You choose the separator character used to join the values before hashing.

Flexible Output Formats

For SHA-based and MD5 algorithms, choose between hexadecimal and Base64 output encoding. Hexadecimal is the default and most widely compatible; Base64 produces shorter strings when storage space matters.

Works Across All CRM Object Types

The Hash Data action is available in contact, company, deal, and ticket workflows, so you can hash property values on any standard HubSpot object.

Quick Start

1. Install the app in your HubSpot portal (see the Installation Guide)
2. Open a HubSpot workflow and add the Hash Data action
3. Configure the primary value, algorithm, and output format
4. Test by enrolling a record and checking the hashed output
