Description

A CE C toolchain library -- for use with LIBLOAD. Use and invoke this library just as you would any of the CE C standard libraries.

A library providing industry-standard cryptography for the TI-84+ CE graphing calculator. Contains a secure hardware-based RNG, Advanced Encryption Standard (128, 192, 256-bit) and RSA public key encryption (1024-2048 bit), SSL signature verification, SHA-256, SHA-256 HMAC, PBKDF2 and more. See the enclosed documentation for details.
Included in this release is enhanced side-channel resistance measures, including: (1) the purging of the stack frame in user-facing encryptor functions, and (2) disabling system interrupts to prevent attempts to initiate system-level USB activity while the library is doing stuff.
