The NSA is responsible for the encryption-related components in these legacy systems:

The NSA has specified [[NSA Suite A Cryptography|Suite A]] and [[NSA Suite B Cryptography|Suite B]] cryptographic algorithm suites to be used in U.S. government systems; the Suite B algorithms are a subset of those previously specified by [[National Institute of Standards and Technology|NIST]] and are expected to serve for most information protection purposes, while the Suite A algorithms are secret and are intended for especially high levels of protection.<ref name="suitB" />
