cryptotensors
experimentalv0.2.3
CryptoTensors is an extension of safetensors that adds encryption, signing, and access control (Rego-based policy engine) while maintaining full backward compatibility with the safetensors format. It provides functions to read and write safetensors which aim to be safer than their PyTorch counterpart.

safetensors
growingv0.7.0
Provides functions to read and write safetensors which aim to be safer than their PyTorch counterpart. The format is 8 bytes which is an unsized int, being the size of a JSON header, the JSON header refers the `dtype` the `shape` and `data_offsets` which are the offsets for the values in the rest of the file.
