comment Pseudorandom function library
I'd first use HMAC-SHA-2 to reduce the input to a fixed size key and then use that key in a stream cipher to obtain arbitrary length output.

@xxx I have deleted my comment mentioning your original name. But please refrain from vandalizing the question or my answer. You asked the question and can't take it back.

You could use a mode that only requires encryption, such as CTR mode.

comment Why does NaCL have different keys for signing and encryption?
NaCl uses authenticated encryption (crypto_box). You can use crypto_box for authentication (typically with long term keys) and confidentiality (typically with ephemeral keys). Sharing long term keys between signatures and crypto_box based authentication is useful.

comment Strategies for securing public key storage on software
Obfuscation isn't enough, but that doesn't mean there is something better either. Software DRM inherently relies on security through obscurity.
