包路径：org.bouncycastle.asn1.x509.SubjectPublicKeyInfo
类名称：SubjectPublicKeyInfo
方法名：parsePublicKey

SubjectPublicKeyInfo.parsePublicKey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

代码示例来源：origin: stackoverflow.com

byte[] encoded = publicKey.getEncoded();
SubjectPublicKeyInfo subjectPublicKeyInfo = new SubjectPublicKeyInfo(
  ASN1Sequence.getInstance(encoded));
byte[] otherEncoded = subjectPublicKeyInfo.parsePublicKey().getEncoded();

代码示例来源：origin: stackoverflow.com

PublicKey pub = pair.getPublic();
byte[] pubBytes = pub.getEncoded();

SubjectPublicKeyInfo spkInfo = SubjectPublicKeyInfo.getInstance(pubBytes);
ASN1Primitive primitive = spkInfo.parsePublicKey();
byte[] publicKeyPKCS1 = primitive.getEncoded();

@SneakyThrows
public static String convertPublicKeyFromX509ToPkcs1Pem(final byte[] publicKeyX509) {
 // Convert public key from X.509 SubjectPublicKeyInfo to PKCS1:
 final ASN1Primitive publicKeyPrimitive = SubjectPublicKeyInfo.getInstance(publicKeyX509).parsePublicKey();
 return pem(publicKeyPrimitive.getEncoded(), RsaKey.KEY_FORMAT_PKCS1, RsaKey.KEY_TYPE_PUBLIC);
}
