Plaintext

What is Plaintext?

Unencrypted data or information that has not been transformed by a cryptographic algorithm. Plaintext is readable by anyone who has access to it and must be protected through encryption when confidentiality is required.

What the standards actually require on plaintext

Requirements naming plaintext across 4 standards, quoted from the control text.

Provide secrets to containers at runtime through a managed secrets system rather than environment variables or mounted files in plaintext. Rotate secrets on schedule and revoke them when a workload is decommissioned.

SP800-190-3.20 · Secrets Management at Runtime
PCI P2PE1 control

The decryption environment where account data is converted from ciphertext to plaintext must be logically isolated, hardened, and protected by strong access controls compliant with PCI DSS.

Domain-4.1 · Decryption Environment Logical Security

Manufacturers should ensure credentials, cryptographic keys and other security parameters are stored securely on the device and not in plaintext.

Questions people ask about plaintext

What is Plaintext?
Unencrypted data or information that has not been transformed by a cryptographic algorithm. Plaintext is readable by anyone who has access to it and must be protected through encryption when confidentiality is required.
Why is Plaintext important for compliance?
Plaintext is a key concept in Information Security. Understanding plaintext helps organizations meet regulatory requirements, reduce risk, and demonstrate due diligence during audits. Our compliance platform maps 686 frameworks with 311K cross-framework control mappings.
Which compliance frameworks address Plaintext?
Plaintext appears in the requirement text of India Account Aggregator Framework (RBI), NIST SP 800-190, PCI P2PE, UK Product Security and Telecommunications Infrastructure Act (PSTI). Across these standards we have identified 4 controls that name it directly, each linked to the control text on the compliance platform.
Where can I learn more about Plaintext?
Explore our compliance framework pages to see how plaintext applies across different standards and regulations. Our implementation guides provide step-by-step guidance, and the compliance platform offers AI-powered analysis of how this concept maps across 686 frameworks.
