pc_steelcrypt 1.1.1

A Dart library implementing cryptographic algorithms and primitives, modeled on the BouncyCastle library.

Changelog

Version 1.1.1

• Fixed OAEPEncoding and PKCS1Encoding to use provided output offset value.
• Fixed RSA block length and offset checks in RSAEngine.processBlock.
• Fixed RSASigner.verifySignature to return false when signature is bad.
