ConvertByteArrayToBoolArray converts a packed []byte back to a []bool.

GetRandomBytes returns random bytes of length.

Return a random generator of RQn with high probability.

Generate a random element in the group of all the elements in Z/nZ that has a multiplicative inverse.

GetRandomQuadraticNonResidue returns a quadratic non residue of odd n.

GetRandomSafePrimesConcurrent tries to find safe primes concurrently.

MustGetRandomInt panics if it is unable to gather entropy from `io.Reader` or when `bits` is <= 0.

Returns true when the byte slice is non-nil and non-empty.

Returns true when all of the slices in the multi-dimensional byte slice are non-nil and non-empty.

PadToLengthBytesInPlace pad {0, ...} to the front of src if len(src) < length output length is equal to the parameter length.

RejectionSample implements the rejection sampling logic for converting a SHA512/256 hash to a value between 0-q.

SHA-512/256 is protected against length extension attacks and is more performant than SHA-256 on 64-bit architectures.

SHA512_256i_TAGGED tagged version of SHA512_256i.

ErrGeneratorCancelled is an error returned from GetRandomSafePrimesConcurrent when the work of the generator has been cancelled as a result of the context being done (cancellation or timeout).

Container for output signatures, mostly used for marshalling this data structure to a mobile app.

TrackingID is used to track the specific session when multiple sessions are running in parallel.
