pointycastle 2.0.0-rc2

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

Changelog

Version 2.0.0-rc2 (2020-02-25)

• Linter Fixes
• Updates to ASN1 API

Version 2.0.0-rc1 (2020-09-11) (Dart SDK version 2.1.1)::q!

• 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.
• Add HKDF support (IETF RFC 5869)
• Add Poly1305, ChaCha20, ChaCha7539, AES-GCM, SHA3, Keccak, RSA/PSS
• Add CSHAKE, SHAKE
• Fixed randomly occurring bug with OAEP decoding.
• Added NormalizedECDSASigner that wraps ECDSASigner to guarantee an ecdsa signature in lower-s form. (Enforcement on verification supported).
• Reduce copies in CBC mode.
• Linter issues fixed.
• FixedSecureRandom to use seed only once.
• ASN1 - BOOLEAN, INTEGER, BIT_STRING, OCTET_STRING, NULL, OBJECT_IDENTIFIER, ENUMERATED, UTF8_STRING, SEQUENCE, SET, PRINTABLE_STRING, IA5_STRING & UTC_TIME
• ASN1 Encoding - DER & BER
• RSA Keys - Private Key carries public key exponent, added publicExponent and privateExponent where necessary and deprecated single variable getters in for those values.

Thanks, Steven

At this release the Point Castle Crypto API has been fully handed over to the Legion of the Bouncy Castle Inc. Steven Roose, it is no small thing to single headedly manage a cryptography API and your effort is rightfully respected by the Pointy Castle user base. We would like to thank you for your trust in us to carry the project forward, and we wish you all the best!
