outbuffer to store the derived key, must be of out_len bytes
out_lenthe desired length of the key to produce
passphrasethe password to derive the key from
salta randomly chosen salt
salt_lenlength of salt in bytes
milliseconds_to_runif iterations is zero, then instead the PBKDF is run until milliseconds_to_run milliseconds has passed

Decode some previously encoded shares using certain ZFEC parameters.

Parameters

Nthe total number of shares
indexesThe index into the encoder's outputs for the corresponding element of the inputs array. Must be of length K.
inputsK previously encoded shares to decode
shareSizethe length in bytes of each input
