Strictly not for use in statistical analysis. Non-reproducible and with unknown statistical properties. Provides an alternative source of randomness from the Mbed TLS library for purposes such as cryptographic key generation. Mbed TLS uses a block-cipher in counter mode operation, as defined in NIST SP800-90A: Recommendation for Random Number Generation Using Deterministic Random Bit Generators. The implementation uses AES-256 as the underlying block cipher, with a derivation function, and an entropy collector combining entropy from multiple sources including at least one strong entropy source.
Value
A length n
raw vector, or length one vector of 2n
random
characters, depending on the value of convert
supplied.
