The z15 supported cryptography functions for z/VSE, z/TPF, and Linux on Z are listed in  Table 7-11. a. PTFs might be required for toleration support or exploitation of z15 features and functions. b. Support statement varies based on Linux on Z distribution and release. c. z/TPF supports only AES-128 and AES-256. d. z/TPF supports only SHA-1 and SHA-256. e. Requires TKE 9.1 or newer. 7.4 Support by features and functions Table 7-11 Supported cryptography functions for z/VSE, z/TPF, and Linux on Z This section addresses operating system support by function. Only the currently in-support  releases are covered. Tables in this section use the following convention: GLYPH<SM590000> N/A: Not applicable GLYPH<SM590000> NA: Not available Chapter 7.
