Ensuring correct cryptographic algorithm and provider usage at compile time
Weitian Xing, Yuanhui Cheng, Werner Dietl · 2021
Using cryptographic APIs to encrypt and decrypt data, calculate digital signatures, or compute hashes is error prone. Weak or unsupported cryptographic algorithms can cause information leakage and runtime exceptions, such as a NoSuchAlgorithmException in Java. Using the wrong cryptographic service provider can also lead to unsupported cryptographic algorithms. Moreover, for Android developers who want to store their key material in the Android Keystore, misused cryptographic algorithms and providers make the key material unsafe.
