SHA-256 Digital Signature Support provides the ability for users to create and verify digital signatures using the latest security standards. Digital signature support was originally provided by four APIs, tpf_RSA_sign_data, tpf_RSA_sign_digest, tpf_RSA_verify_data, and tpf_RSA_verify_digest which used either MD5 or SHA1 as the message digest algorithm. Eight new functions were created to create and verify digital signatures that use SHA-256 as the message digest algorithm. The tpf_RSA_sign and tpf_RSA_verify functions are used for contiguous...

Starting with the first APAR that is shipped in January 2020, the z/TPF and z/TPFDF APAR tar files will contain only source files and object code only (OCO) binaries. Generated files (objects, shared objects, listings, and map files) will no longer be included in the APAR tar files. These files must be generated when the APAR is installed. Please see Service bulletin 202 for complete details.
PJ45579 provides a number of enhancements such as support for path parameters, JSON only names, XML attributes, and the ability to define request specific string encodings. The following enhancements were included: REST provider support and REST consumer support include path parameters in the input request structure when you specify the path parameter in the OpenAPI descriptor . To map the path field in the input request structure, the path parameter must match a DFDL element name. REST provider and REST consumer support URL encoding for path... [More]

The TPF Lab will be closed on Thursday and Friday, July 4th and 5th, for the U.S. 4th of July holiday. The Lab will resume normal operations on Monday, July 8. If you have a critical situation that requires immediate assistance, please open a Severity 1 PMR/ETR and offshift support will be notified. (For more information, go to Opening Problems with the Service Request Too l.)
z/TPFDF variable-length algorithm support provides support for variable-length algorithms in z/TPFDF basic indexes, as well as a variable-length hashing algorithm. Previously, you were required to define the maximum length of key data for a specific file ID and index path combination. LRECs in index files would be created with space reserved for the maximum key length, regardless of the actual key size. Sizes of the actual key data for a single definition can differ greatly. This potentially leads to wasted space in the subfile, which also... [More]
