pybitmessage.highlevelcrypto module¶
High level cryptographic functions based on pyelliptic
OpenSSL bindings.
Note
Upstream pyelliptic was upgraded from SHA1 to SHA256 for signing. We must upgrade PyBitmessage gracefully. More discussion.
-
makeCryptor
(privkey)[source]¶ Return a private
pyelliptic.ECC
instance
-
sign
(msg, hexPrivkey, digestAlg='sha256')[source]¶ Signs with hex private key using SHA1 or SHA256 depending on digestAlg keyword.
-
pointMult
(secret)[source]¶ Does an EC point multiplication; turns a private key into a public key.
Evidently, this type of error can occur very rarely:
>>> File "highlevelcrypto.py", line 54, in pointMult >>> group = OpenSSL.EC_KEY_get0_group(k) >>> WindowsError: exception: access violation reading 0x0000000000000008
