Encryption for Your Data Across Transit & Rest

Indigo e-Sign uses robust encryption for data in transit and data at rest to help protect information stored and transferred through the platform.

Secure Data in Transit (HTTPS / TLS)

Data transmitted between your device and Indigo e-Sign is protected using HTTPS/TLS encryption. This helps prevent sensitive information from being exposed or intercepted while it is being transmitted.

Encrypted Data Storage at Rest

Indigo e-Sign uses encryption to protect data when stored on our servers. The platform's security measures ensure your files are isolated and protected against unauthorized physical and digital access.

256-Bit Advanced Encryption

Indigo e-Sign highlights 256-bit encryption as an essential foundation of its document security, guarding high-value contracts and signing data throughout the lifecycle.

Cipher Integrity Status
Active • 256-Bit
Transit Protocol TLS 1.3 / HTTPS
Storage Cipher AES-256-GCM
Key Hashing PBKDF2 SHA-256

All documents, metadata, and signing tokens undergo continuous cryptographic verification to maintain complete data privacy.

Access Architecture

Protecting Access to Your Documents

Encryption is only one part of keeping documents secure. Indigo e-Sign employs multi-tiered access controls and authentication mechanisms to prevent unauthorized entry.

Secure Token-Based Access

Participants access signing sessions through unique, time-limited cryptographic tokens. This provides strictly controlled, expiring access during the execution process.

Role-Based Access Controls (RBAC)

Indigo e-Sign uses role-based access controls and authentication to manage who can create, send, review, and sign documents within your organization.

Salted Password Hashing Protection

User credentials are protected using Django's industry-standard PBKDF2 password-hashing algorithm with unique cryptographic salts, never stored as plain-text.

Integration Security

Protecting Cloud Storage Connections

If you connect supported cloud storage services such as Google Drive, Dropbox, or Microsoft OneDrive, Indigo e-Sign handles your integrations with strict isolation protocols.

Encrypted OAuth 2.0 Tokens

Indigo e-Sign uses OAuth 2.0 to access files on your behalf. These OAuth tokens are encrypted using dedicated cryptographic keys and stored securely in isolated databases.

Instant Revocation & Disconnect

You maintain full control. You can disconnect integrated cloud storage accounts at any moment, instantly wiping cached tokens and revoking platform permissions.
