RSA_private_decrypt returns -1. You should not pass 1 to RSA_private_decrypt but the length of the block you are trying to. This complete sample program. This article describes how to decrypt private key using OpenSSL on NetScaler. How to Decrypt an RSA Private Key Using OpenSSL. Example:-----BEGIN RSA PRIVATE. Phpseclib's PKCS#1 v2.1 compliant RSA implementation is feature rich and has pretty much zero server requirements above and beyond PHP. This article describes how to decrypt private key using OpenSSL on NetScaler. How to Decrypt an RSA Private Key Using OpenSSL. Example:-----BEGIN RSA PRIVATE.

Hey, first of all, thanks a lot for this awesome text. I was just wondering, when I run the program as is, I get the following output: Original Text: Text to be encrypt Encrypted Text: [B@33c26386 Decrypted Text: Text to be encrypt Now this looks alright, but correct me if I’m wrong.

The second output [B@33c26386 is just a location in memory, not what is actually stored there. What should I do if I wanted to do some further editing on the encrypted text ie. Send it to someone?

Again, thank you very much for this 🙂. Admin, Thanks for this well written and useful code. What type of key files are the private.key and public.key files this code is generating? Are they binary DER-encoded format?

If so, why does this OpenSSL command not work trying to convert it to a.pem file? Scramby V 2 0 40 Keygenguru. I tried openssl x509 -inform def -in public.key -out public.pem unable to load certificate 10684:error:0D07207B:asn1 encoding routines:ASN1_get_object:header too long:asn1_lib.c:150: as well as openssl pkcs12 -in public.key -out public.pem 8080:error:0D07207B:asn1 encoding routines:ASN1_get_object:header too long:asn1_lib.c:150: I am trying to get the exponent and modulus from the public key to use in a Javascript encryption library and I think I could get them from a pem version of the key using openssl. Thanks, Brian. The code is just writing the PrivateKey and PublicKey object to the file, not the actual keys.
