hashfields

Selectively hash, drop, or keep fields from a flat file (e.g. CSV).

Install with pip:

pip install hashfields

Or visit the Releases page for pre-built, self-contained executables.

Example

Given this input CSV:

column1,column2,column3,column4
r1c1,r1c2,r1c3,r1c4
r2c1,r2c2,r2c3,r2c4
r3c1,r3c2,r3c3,r3c4
r4c1,r4c2,r4c3,r4c4

And this configuration:

SHA256 hash algorithm
drop column1, column3
skip column2

E.g.

echo "column1,column2,column3,column4
r1c1,r1c2,r1c3,r1c4
r2c1,r2c2,r2c3,r2c4
r3c1,r3c2,r3c3,r3c4
r4c1,r4c2,r4c3,r4c4" | hashfields --alg sha256 --drop column1 column3 --skip column2

hashfields produces this CSV:

column2,column4
r1c2,fb66e41761a74ea0c042e1c226c04fa2ce1a1334d7063d86230d17f33f109b68

r3c2,7e32c53b7729f5dce7ac54232b7f2d93d6c78ed19fc8d096b0fde948f513e9dc
