SubjectPublicKeyInfo.getPublicKey介绍

[英]for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.
[中]因为，当公钥是一个编码对象时——如果无法解码位字符串，该例程将抛出IOException。

代码示例

byte[] keyBytes = key.getEncoded(); // X.509 for public key
SubjectPublicKeyInfo subPkInfo = new SubjectPublicKeyInfo((ASN1Sequence)ASN1Object.fromByteArray(keyBytes));
byte[] rsaformat = subPkInfo.getPublicKey().getDEREncoded();

    // get the CN
    String cn = (String) ((X509Name) req.getCertificationRequestInfo().getSubject()).getValues(new DERObjectIdentifier("2.5.4.3")).get(0);

  catch (NoSuchAlgorithmException | InvalidKeySpecException e)
