PRNG descriptor

Fields

name: *const c_char

Name of the PRNG

export_size: c_int

size in bytes of exported state

start: Option<unsafe extern "C" fn(prng: *mut prng_state) -> c_int>

Start a PRNG state @param prng [out] The state to initialize @return CRYPT_OK if successful

add_entropy: Option<unsafe extern "C" fn(in_: *const c_uchar, inlen: c_ulong, prng: *mut prng_state) -> c_int>

Add entropy to the PRNG @param in The entropy @param inlen Length of the entropy (octets)
@param prng The PRNG state @return CRYPT_OK if successful

ready: Option<unsafe extern "C" fn(prng: *mut prng_state) -> c_int>

Ready a PRNG state to read from @param prng The PRNG state to ready @return CRYPT_OK if successful

read: Option<unsafe extern "C" fn(out: *mut c_uchar, outlen: c_ulong, prng: *mut prng_state) -> c_ulong>

Read from the PRNG @param out [out] Where to store the data @param outlen Length of data desired (octets) @param prng The PRNG state to read from @return Number of octets read

done: Option<unsafe extern "C" fn(prng: *mut prng_state) -> c_int>

Terminate a PRNG state @param prng The PRNG state to terminate @return CRYPT_OK if successful

pexport: Option<unsafe extern "C" fn(out: *mut c_uchar, outlen: *mut c_ulong, prng: *mut prng_state) -> c_int>

Export a PRNG state @param out [out] The destination for the state @param outlen [in/out] The max size and resulting size of the PRNG state @param prng The PRNG to export @return CRYPT_OK if successful

pimport: Option<unsafe extern "C" fn(in_: *const c_uchar, inlen: c_ulong, prng: *mut prng_state) -> c_int>

Import a PRNG state @param in The data to import @param inlen The length of the data to import (octets) @param prng The PRNG to initialize/import @return CRYPT_OK if successful

test: Option<unsafe extern "C" fn() -> c_int>

Self-test the PRNG @return CRYPT_OK if successful, CRYPT_NOP if self-testing has been disabled
