Locktera combines cryptographic digests with AES-256 encryption to enhance your data security. A cryptographic digest, also known as a hash, creates a fixed-length, unique representation of your data, ensuring its integrity by detecting any unauthorized modifications. AES-256 encryption then protects your data by encrypting it with a 256-bit key, making it nearly impossible for attackers to decrypt without the proper key. Together, the cryptographic digest ensures your data hasn’t been altered, while AES-256 provides strong encryption to protect it from unauthorized access, ensuring your data remains secure and intact.

Locktera leverages cryptographic digests as a key security measure to ensure the integrity, authentication, and non-repudiation of your data across its platform. Here's how Locktera uses cryptographic digests:

Data Integrity Verification:
Locktera generates a cryptographic hash (digest) of your sensitive data before it's transmitted or stored. This hash acts like a unique fingerprint, ensuring the data remains intact and unmodified. When the data is accessed, Locktera recalculates the hash and compares it to the original digest. If the digests match, the data is confirmed unchanged; if they differ, tampering is detected.

Digital Signatures and Authentication:
Locktera uses cryptographic digests alongside digital signatures to sign data containers. The original data is hashed, and the digest is encrypted with the sender’s private key to create the signature. You or the recipient can verify the signature by decrypting the digest with the sender’s public key and comparing it to the hash of the received data. This ensures both the authenticity and integrity of your data.

Efficient Data Comparison:
Instead of comparing entire datasets or documents, Locktera uses cryptographic digests to compare hash values, allowing quick and efficient data comparison. This makes the process much faster and more resource-efficient.

Audit and Compliance:
Locktera’s use of cryptographic digests ensures that changes to critical data are auditable and traceable. By logging hash values during data processing, Locktera supports compliance with data security regulations and standards, ensuring your data’s integrity is consistently maintained.

By using cryptographic digests, Locktera enhances your data security at every stage, protecting it from tampering and verifying its authenticity and integrity. This is especially valuable in industries where data accuracy and security are critical.
