| A D | ChangeLog | 469 nonce from entropy. Applications were affected if they called
475 entropy from the nonce.
1032 entropy function to obtain entropy for a nonce if the entropy size is less
1043 bytes (size of the entropy accumulator).
2263 * Fix the entropy.c module to not call mbedtls_sha256_starts() or
2366 config-no-entropy.h to reduce the RAM footprint.
2550 * Added hardware entropy selftest to verify that the hardware entropy source
2558 library features that do not require an entropy source.
3417 * Ability to force the entropy module to use SHA-256 as its basis
4125 entropy sources
