The following errata report has been rejected for RFC7748, "Elliptic Curves for Security". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid5568 -------------------------------------- Status: Rejected Type: Technical Reported by: Juan Alcasabas <juan.alcasabas@gmail.com> Date Reported: 2018-12-07 Rejected by: Stanislav Smyshlyaev (IRSG) Section: 5.2 Original Text ------------- Input u-coordinate: e5210f12786811d3f4b7959d0538ae2c31dbe7106fc03c3efc4cd549c715a493 Corrected Text -------------- Input u-coordinate: e5210f12786811d3f4b7959d0538ae2c31dbe7106fc03c3efc4cd549c715a413 Notes ----- In the X25519 2nd test vector the last byte of input u-coordinate should be 13 instead of 93. This will fix inconsistency between u-coordinate, its base10 representation and the output u-coordinate. --VERIFIER NOTES-- A change of one bit of the input u-coordinate in the hexadecimal representation is proposed (to make it "consistent" with the base 10 representation). However, implementations of x25519 should "mask" that bit after taking a u-coordinate as an input - therefore, the existing text of RFC does not have any errors there. -------------------------------------- RFC7748 (draft-irtf-cfrg-curves-11) -------------------------------------- Title : Elliptic Curves for Security Publication Date : January 2016 Author(s) : A.
