Question

Trying to figure out why my base64 sha1’s are different.

I get

Password ‘a’ Result ‘hvfkN/qlp/zhXR3cuerq6jd2Z7g=’

When using my java function. I can verify that using some random online tools.

However when I try to verify using the command line and openssl

echo a | openssl dgst -binary -sha1 | openssl base64

I get

P3hoUOOHVQ/auDbtfm3Igd4jABs=

That maybe it was utf8/bash thing, so I tried

echo 'a' | iconv --from-code=ISO-8859-1 --to-code=UTF-8 | openssl dgst -binary -sha1 | openssl base64

Same result.

What am I missing?

echo appends a newline, which will be included in the digest computation; try printf instead. Also be wary of other parts of the pipeline adding extraneous newlines or other characters.
