Pure Python crypto library

This library isn't any better than any other library. I make no claims about speed, memory usage, or any other metric by which you would measure a library. It's not regularly maintained (I do this in my limited spare time). It's just a side project I've been meaning to take on for a while.

This has been a useful side project in that it has:

• forced me to read algorithm specifications, which has demystified those algorithms
• let me experiment with ideas regarding what an easy-to-use crypto API should look like

This library will include algorithms I like, and won't include any I don't. This means:

Included:

• AES-GCM
• AES-CTR-DRBG

To be included (eventually):

• RSA-PSS
• RSA-OAEP
• SHA-256 (384, 512)
• Simon, Speck (using HMAC-SHA256 for AE?)
• ECDHE/ECDSA (P-256, 384, 521)

To never be included:

• DES/3DES
• RSA-PKCS1 (sign or encrypt)
• RC4
