decrypted contentCurrently the library supports:
-
EncryptedKey to transport symmetric key using:
- http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p
- http://www.w3.org/2001/04/xmlenc#rsa-1_5 (Insecure Algorithm)
-
EncryptedData using:
Insecure Algorithms can be disabled via disallowEncryptionWithInsecureAlgorithm/disallowDecryptionWithInsecureAlgorithm flags when encrypting/decrypting. This flag is off by default in 0.x versions.
A warning will be piped to stderr using console.warn() by default when the aforementioned algorithms are used. This can be disabled via the warnInsecureAlgorithm flag.
