Struct pkcs1::UIntRef

source · [−]

pub struct UIntRef<'a> { /* private fields */ }

Expand description

“Big” unsigned ASN.1 INTEGER type.

Provides direct access to the underlying big endian bytes which comprise an unsigned integer value.

Intended for use cases like very large integers that are used in cryptographic applications (e.g. keys, signatures).
