Hi , guys
I have use the follow openssl commands to create a key pair for android app signing. Follow this link https://source.android.com/docs/core/ota/sign_builds#manually-generating-keys # generate RSA key openssl genrsa -3 -out temp.pem 2048 Generating RSA private key, 2048 bit long modulus ....+++ .....................+++ e is 3 (0x3) # create a certificate with the public part of the key openssl req -new -x509 -key temp.pem -out releasekey.x509.pem -days 10000 -subj '/C=US/ST=California/L=San Narciso/O=Yoyodyne, Inc./OU=Yoyodyne Mobility/CN=Yoyodyne/emailAddress=yoyod...@example.com' # create a PKCS#8-formatted version of the private key openssl pkcs8 -in temp.pem -topk8 -outform DER -out releasekey.pk8 -nocrypt # securely delete the temp.pem file shred --remove temp.pem The key file was successfully generated, but when I compile the entire project signature app, the following error is reported: java.security.NoSuchAlgorithmException: 1.2.840.113549.1.5.13 SecretKeyFactory not available at java.base/javax.crypto.SecretKeyFactory.<init>(SecretKeyFactory.java:122) at java.base/javax.crypto.SecretKeyFactory.getInstance(SecretKeyFactory.java:168) at com.android.signapk.SignApk.decryptPrivateKey(SignApk.java:250) at com.android.signapk.SignApk.readPrivateKey(SignApk.java:272) at com.android.signapk.SignApk.main(SignApk.java:1210) My ubuntu version is 20.04.4 LTS openjdk version is 11.0.15 2022-04-19 openssl version is 1.1.1r-dev built on Mon Aug 22 11:19:51 2022 UTC Any help is welcome. ****************************************************** 努比亚技术有限公司 基础框架团队 李周华 联系电话:18706866323 地址:西安市高新唐延南路10号中兴产业园A座101 Email:0016003...@nubia.com ******************************************************
