comment Should I use md5 for my new application?
It used to be a non-security application. The plan was to re-use the file for signing.

comment Should I use md5 for my new application?
The other day I made the argument that md5 should be replaced with sha-256 in a particular application. I wanted to sign the file digests. I was stunned by the fervent opposition to what I thought was a completely innocuous change. So I am asking for advice about how to better explain the harmlessness of strong hashing to my peers.

comment Signatures: RSA compared to ECDSA
Signing, verification, and key generation are all very fast in the Ed25519 implementation.

comment How do I construct a 256-bit hash function from 128-bit AES?
@D.W. I do actually need a MAC, but I'm interested in the answer to the stated question. I may ask another question about implementing MACs on constrained devices.

Thanks for the useful advice on key lengths and the inapplicability of the birthday paradox. I probably will use CBC-MAC or CMAC (for variable-length messages according to Wikipedia) for my application.

Doesn't the birthday paradox mean a 128-bit hash only provides 64 bits of security when looking for collisions?
