Description

Used PDFbox for document download but for encryption it is currently pointing to MD5. I want to avoid using of MD5 and use only AES. Can you suggest what changes I need to follow to achieve the AES encryption

 

java.security.MessageDigest.getInstance(MessageDigest.java:192)
org.apache.pdfbox.pdmodel.encryption.MessageDigests.getMD5(MessageDigests.java:39)
org.apache.pdfbox.pdmodel.encryption.StandardSecurityHandler.prepareEncryptionDictRev2345(StandardSecurityHandler.java:500)
org.apache.pdfbox.pdmodel.encryption.StandardSecurityHandler.prepareDocumentForEncryption(StandardSecurityHandler.java:394)

can you provide information on this package on how to implement AES encryption?
