Is ASCII armoring supported?

[mgrossmann]

Hi there,

first of all many thanks for implementing my change suggestion from pull request #6. Today I would like to ask if decrypting ASCII armored data is already supported.

Greetings Mike

Hi @mgrossmann, sure, e.g. in DecryptionStreamFactoryTest.java 48-68 and 296-395 you can see it is supported transparently:
