To ensure the secure and efficient use of SecureCRT 8.1, users should follow best practices for license key management:

| Element | Description | |---------|-------------| | | • Single‑User (per‑user) – tied to a specific Windows/Mac/Linux user account. • Floating (Network) License – a pool of seats managed by a license server, useful for teams. | | License Duration | • Perpetual – one‑time purchase, unlimited use of the version you bought (you may upgrade by buying a new version or a maintenance plan). • Subscription – annual/renewable term, includes upgrades and support for the subscription period. | | Activation Mechanism | SecureCRT stores the license key in a hidden file ( license.dat on Windows, ~/Library/Application Support/VanDyke Software/SecureCRT/license.dat on macOS, ~/.vandyke/SecureCRT/license.dat on Linux). The key is encrypted and bound to the machine’s hardware fingerprint (CPU, motherboard, MAC address, etc.). | | Key Format | A 25‑character alphanumeric string split into five blocks (e.g., ABCD1-EFGH2-IJKL3-MNOP4-QRST5 ). The string itself is not the raw license; it is a signed token that the SecureCRT client validates against the embedded public key of VanDyke. | | Validation | On startup SecureCRT reads license.dat , decrypts the token, verifies the signature, checks the hardware fingerprint, and confirms that the license is still within its validity period (if subscription‑based). |
