The relevant packets will be considered unsupported instead of malformed.
Hence, parsing them will succeed by default (based on
`config.ignoreUnsupportedPackets`).
- Use PascalCase for classes, with uppercase acronyms.
- Use camelCase for function and variables. First word/acronym is always
lowercase, otherwise acronyms are uppercase.
Also, make the packet classes' `tag` properties `static`.
Refactor functions to take the configuration as a parameter.
This allows setting a config option for a single function call, whereas
setting `openpgp.config` could lead to concurrency-related issues when
multiple async function calls are made at the same time.
`openpgp.config` is used as default for unset config values in top-level
functions.
`openpgp.config` is used as default config object in low-level functions
(i.e., when calling a low-level function, it may be required to pass
`{ ...openpgp.config, modifiedConfig: modifiedValue }`).
Also,
- remove `config.rsaBlinding`: blinding is now always applied to RSA decryption
- remove `config.debug`: debugging mode can be enabled by setting
`process.env.NODE_ENV = 'development'`
- remove `config.useNative`: native crypto is always used when available
This PR adds four config options to configure whether and how to load
indutny/elliptic: use_indutny_elliptic, external_indutny_elliptic,
indutny_elliptic_path and indutny_elliptic_fetch_options.
Also:
- Use tweetnacl.js instead of indutny/elliptic for curve25519 key generation
- Don't initialize indutny's curve25519, improving performance when using that curve
- Verify NIST signatures using Web Crypto instead of indutny/elliptic when not streaming
- Move KeyPair.sign/verify to ecdsa.js
- Move KeyPair.derive to ecdh.js
- Move keyFromPrivate and keyFromPublic to a new indutnyKey.js file
* Various FIXME tags are removed
* In curve.js:
- webCrypto/nodeCrypto fallback bug is fixed
- Curve25519 has keyType ecdsa (won't be used for signing, but technically can be)
- webGenKeyPair is simplifed
* In base64.js:
- documentation added and arguments simplified
* In ecdsa.js and eddsa.js:
- hash_algo is now at least as strong as the default curve hash
- simplified the code by moving webSign/nodeSign and webVerify/nodeVerify to live in key.js (ht @ismaelbej)
* In message.js:
- in decryptSessionKey, loops break once a key packet is decrypted
* In key.js:
- getPreferredHashAlgorithm returns the best hash algorithm
- enums are used for curve selection
