https://issues.dlang.org/show_bug.cgi?id=13804 Issue ID: 13804 Summary: BigInt have no binary interface to be used in crypto Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: Phobos Assignee: nobody puremagic.com Reporter: golovanov_alexey mail.ru We have no properties and methods in BigInt to work with binary data to use BigInt in crypto (for example in RSA). BigInt have no constructor from binary data - ubyte[], uint[], etc. To use BigInt in crypto, we need ability: 1 - create BigInt from bytes; 2 - make calculations; 3 - get bytes from result BigInt. In step (2) we need access to underlying data BigDigit[] to implement absent powMod method "(a pow b) mod c"). Programmers cant't use std.bigint and forced to reimplement biguintcore.d and bigint.d .
