%description
Cryptographic functions over raw vectors, including message digests of
in-memory data, files and connections, keyed-hash message authentication
codes (HMAC), Advanced Encryption Standard (AES) encryption, constant-time
comparison and hexadecimal encoding, backed by a bundled and pinned copy
of the 'Mbed TLS' project's cryptography library, 'TF-PSA-Crypto'
(<https://github.com/Mbed-TLS/TF-PSA-Crypto>). No system cryptographic
library, 'Java' or 'Python' is required at install or run time. Algorithm
names are matched exactly, and failures are reported as structured
conditions. The same primitives, and secure erasure of native buffers, are
published to other packages as a static archive and as a registered C
interface, so that a package can call them from C without going through R.
