问题 I am obtaining a Google Play API key from Google, and it is asking to enter SHA1 fingerprint. I want to know what is SHA1 fingerprint? I also wanted to know weather this API key can be used from another computer/pc? 回答1: It is a standard for the implementation of a 'secure hash algorithm' - a one-way cryptographic function that can be used to act as a 'signature' of a sequence of bytes.

PHP SSL Certificate Fingerprint

I'm looking for a totally free fingerprint reader API/SDK that I can use in my Java project. The standard for such things is called BioAPI and you might have luck searching by "bioapi java". Our experience shows that different hardware vendors have their own SDKs and not all of them support BioAPI. 来源： https://stackoverflow.com/questions/6549801/is-there-a-free-fingerprint-reader-api-sdk-for-java
