两个实用的方法从Base64字符串生成RSAPublicKey及RSAPrivatekey详解编程语言

 1     public static RSAPublicKey getRSAPublidKeyBybase64(String base64s) { 
 2         X509EncodedKeySpec keySpec = new X509EncodedKeySpec(CodeUtils.base64Decode(base64s)); 
 3         RSAPublicKey publicKey = null; 
 4  
 5         try { 
 6             publicKey = (RSAPublicKey)keyFactory.generatePublic(keySpec); 
 7         } catch (InvalidKeySpecException var4) { 
 8             LOGGER.error("base64编码=" + base64s + "转RSA公钥失败", var4); 
 9         } 
10  
11         return publicKey; 
12     } 
13  
14     public static RSAPrivateKey getRSAPrivateKeyBybase64(String base64s) { 
15         PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(CodeUtils.base64Decode(base64s)); 
16         RSAPrivateKey privateKey = null; 
17  
18         try { 
19             privateKey = (RSAPrivateKey)keyFactory.generatePrivate(keySpec); 
20         } catch (InvalidKeySpecException var4) { 
21             LOGGER.error("base64编码=" + base64s + "转RSA私钥失败", var4); 
22         } 
23  
24         return privateKey; 
25     }
