Keytool Error Nullpointerexception

This is the accepted answer. keypass must be at least 6 characters long. This is the accepted answer. Otherwise, alias refers to a key entry with an associated certificate chain. have a peek at this web-site

A keystore type defines the storage and data format of the keystore information, and the algorithms used to protect private/secret keys in the keystore and the integrity of the keystore itself. When the option is not provided, the start date is the current time. The CA generates crl_file. Also, can you tell me when IBM will release 1.4.1 ? https://community.igniterealtime.org/thread/20383

The rest of the examples assume you executed the -genkeypair command without options specified, and that you responded to the prompts with values equal to those given in the first -genkeypair After generating a keypair and CSR using the keytool that comes with IBM's JVM, and signing the CSR with a test CA, I am trying to import the PKCS 7 cert Why won't a series converge if the limit of the sequence is 0? In that case it turned out to be a bug in Sun's 1.4.0 code which IBM simply ported.

The fix will be shipped with IBM 1.4.1 jvm Log in to reply. DESCRIPTION keytool is a key and certificate management utility. Multiple lines are used in the examples just for legibility purposes.) This command creates the keystore named "mykeystore" in the "working" directory (assuming it doesn't already exist), and assigns it the Requesting a Signed Certificate from a Certification Authority So far all we've got is a self-signed certificate.

If such an attack took place, and you did not check the certificate before you imported it, you would end up trusting anything the attacker has signed.

So first thing I want to do is change password from the default "changeit" bash-3.00# /usr/jdk/instances/jdk1.5.0/jre/bin/keytool -storepasswd -keystore /usr/jdk/instances/jdk1.5.0/jre/lib/security/cacerts -new newpassword Enter keystore password: changeit keytool error: java.io.IOException: Keystore was tampered KeyStore Entries Keystores may have different types of entries. Using this certificate implies trusting the entity that signed this certificate. (Note that in some cases, such as root or top-level CA certificates, the issuer signs its own certificate.) Validity Period You can not post a blank message.

Also, can you tell me when IBM will release 1.4.1 ? http://www.ca.com/us/services-support/ca-support/ca-support-online/knowledge-base-articles.tec483297.html Any date for 1.4.1 ? This is normally a CA. Which type of import is intended is indicated by the value of the -alias option: If the alias does not point to a key entry, then keytool assumes you are adding

This chain is the one returned by the CA in response to your request (if the CA reply is a chain), or one constructed (if the CA reply is a single I've exported a certificate from the firstkeystore using the following command: keytool -export -alias mykey -file my_home.crt -keystore firstkeystore.keystore producing the following certificate: my_home.crt.

If a source keystore entry type is not supported in the destination keystore, or if an error occurs while storing an entry into the destination keystore, the user will be prompted This is the accepted answer. No, I have not tried ikeyman. Source The Definite Encoding Rules describe a single way to store and transfer that data.

Private Keys These are numbers, each of which is supposed to be known only to the particular entity whose private key it is (that is, it's supposed to be kept secret). More... Importing Keystore The command "importkeystore" is used to import an entire keystore into another keystore, which means all entries from the source keystore, including keys and certificates, are all imported to

Each tool gets the keystore.type value and then examines all the currently-installed providers until it finds one that implements keystores of that type.

If destkeypass is not provided, the destination entry will be protected with the source entry password. We create the KeyStore in the following manner (sample code, suppressing Exception handling for brevity), KeyStore ks = KeyStore.getInstance( "JKS" ); ks.load( null, null ); ... // Add crypto material here Please consult the Java Cryptography Architecture API Specification & Reference for a full list of -keyalg and -sigalg you can choose from. This is specified by the following line in the security properties file: keystore.type=jks To have the tools utilize a keystore implementation other than the default, you can change that line to

If dname is provided, it's used as the subject in the CSR. If you are still having problems please repost and I'll see what can be done. This command was named -export in previous releases. have a peek here The private key is assigned the password specified by .

But when we try to inspect it with keytool we get, keytool -list -keystore nms.keystore keytool error: java.io.EOFException Funny thing is, the same code works perfectly on every other machine that You cannot reproduce the error without the keystore that contains the private key and the p7 cert chain to be imported. Can't a user change his session information to impersonate others? Do you want the keystore file?

This is because you cannot import cert chains unless you have the private key for one of the certs. If the -trustcacerts option has been specified, additional certificates are considered for the chain of trust, namely the certificates in a file named "cacerts". Is it possible to keep publishing under my professional (maiden) name, different from my married legal name? The options for each command may be provided in any order.

It is assumed that CAs will only create valid and reliable certificates, as they are bound by legal agreements. Later, after a Certificate Signing Request (CSR) has been generated (see the -certreq command) and sent to a Certification Authority (CA), the response from the CA is imported (see -importcert), and Importing a Certificate Reply When importing a certificate reply, the certificate reply is validated using trusted certificates from the keystore, and optionally using the certificates configured in the "cacerts" keystore file In the actual code, none of the arguments passed to the store method are null, we have triple-checked that.

Keystore implementations of different types are not compatible.

Log in to reply. There should be a space after 'mykey' This is what happens when you get it right [emailprotected]:/tmp$ keytool -import -alias mykey -file my_home.crt -keystore secondkeystore.keystore Enter keystore password: Owner: CN=Unknown, OU=Unknown, DES). It protects each private key with its individual password, and also protects the integrity of the entire keystore with a (possibly different) password.

An alias is specified when you add an entity to the keystore using the -genseckey command to generate a secret key, -genkeypair command to generate a key pair (public and private I beleive it was the class used to parse the certificate bytes which was returning null for a zero length encoded DER object, relatively low level error.
