Advanced Encryption Standard (AES-256)

AES-256 is a military-grade encryption algorithm that protects sensitive data using a 256-bit key. With 2⁵²⁶ possible key combinations, it is virtually unbreakable by brute-force methods making it the gold standard for data encryption in secure file sharing, especially in compliance-driven industries like legal, finance, and healthcare.

What is AES-256?

The Advanced Encryption Standard (AES) was established by the U.S. National Institute of Standards and Technology (NIST) in 2001 to replace the outdated DES (Data Encryption Standard). AES is a symmetric block cipher, meaning the same key is used for both encryption and decryption. The “256” in AES-256 refers to the key length offering the highest level of encryption strength available within the AES family.

How AES-256 Works

AES-256 encrypts data in fixed blocks of 128 bits using multiple rounds of complex transformations, including substitution, permutation, and mixing. With 14 rounds of encryption, AES-256 makes it nearly impossible for unauthorized users to crack the code, even with modern computing power.

This type of encryption is commonly used to protect:

  • Files stored on cloud servers (encryption at rest)

  • Data transmitted over the internet (encryption in transit)

  • Confidential messages and attachments shared between professionals

Why AES-256 Matters for Compliance

Many of today’s most stringent data protection standards either recommend or require the use of AES-256 encryption, including:

  • HIPAA (for protecting patient health records)

  • PIPEDA and PHIPA (for safeguarding personal data in Canada)

  • GDPR (for privacy in the EU)

  • FIPS 140-2 (used in federal environments)

Because AES-256 provides both strong security and reliable performance, it is trusted by governments, law firms, accounting firms, and regulatory bodies worldwide.

AES-256 in TitanFile

TitanFile uses AES-256 encryption to secure files both at rest and in transit. All files uploaded to TitanFile are automatically encrypted using this standard, ensuring your data remains protected against unauthorized access even if intercepted or stored on a compromised device.

Combined with Transport Layer Security (TLS), granular access controls, audit logs, and optional customer-managed encryption keys (CMEK), TitanFile provides enterprise-grade protection without the complexity.
