unknown object in getInstance: org.bouncycastle.asn1.DERApplicationSpecific #462
Description
Hi,
I'm using a library (https://github.com/markenwerk/java-utils-mail-smime) to encrypt/decrypt SMIME Emails. That library includes BouncCastle.
All emails are decrypted without problems, except those from one client.
Said emails throw this exception:
net.markenwerk.utils.mail.smime.SmimeException: Malformed content. at net.markenwerk.utils.mail.smime.SmimeUtil.handledException(SmimeUtil.java:615) ~[utils-mail-smime-1.0.8.jar:na] at net.markenwerk.utils.mail.smime.SmimeUtil.decrypt(SmimeUtil.java:235) ~[utils-mail-smime-1.0.8.jar:na] at helpers.email.EmailFetcher.decryptMessageIfNecessary(EmailFetcher.java:293) [classes/:na] at helpers.email.EmailFetcher.processMessage(EmailFetcher.java:194) [classes/:na] at helpers.Converter.convertToPDF(Converter.java:59) [classes/:na] Caused by: org.bouncycastle.cms.CMSException: Malformed content. at org.bouncycastle.cms.CMSUtils.readContentInfo(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0] at org.bouncycastle.cms.CMSUtils.readContentInfo(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0] at org.bouncycastle.cms.CMSEnvelopedData.<init>(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0] at org.bouncycastle.mail.smime.SMIMEEnveloped.<init>(Unknown Source) ~[bcmail-jdk15on-1.56.jar:1.56.0.0] at net.markenwerk.utils.mail.smime.SmimeUtil.decrypt(SmimeUtil.java:225) ~[utils-mail-smime-1.0.8.jar:na] Caused by: java.lang.IllegalArgumentException: unknown object in getInstance: org.bouncycastle.asn1.DERApplicationSpecific at org.bouncycastle.asn1.ASN1Sequence.getInstance(Unknown Source) ~[bcprov-jdk15on-1.56.jar:1.56.0] at org.bouncycastle.asn1.cms.ContentInfo.getInstance(Unknown Source) ~[bcprov-jdk15on-1.56.jar:1.56.0] at org.bouncycastle.cms.CMSUtils.readContentInfo(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0] at org.bouncycastle.cms.CMSUtils.readContentInfo(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0] at org.bouncycastle.cms.CMSEnvelopedData.<init>(Unknown Source) ~[bcpkix-jdk15on-1.56.jar:1.56.0.0]
The emails are encrypted using RSA (2048) / AES (256). The email is decrypted in MS Outlook without problems.
Any idea? Thanks!
