Keytool error: java.lang.Exception: Key pair not generated, alias already exists Description You tried to use the blackberry-keytool tool to create a self-signed Developer Certificate. Enter the alias for the new key pair entry and press the OK button. If the current keystore type is not PKCS #12: The Key Pair Entry Password dialog will be displayed. Enter the password to protect the new key pair entry with, confirm it and press the OK button. The new key pair entry will appear in the keystore entries table. Shortcut key: Ctrl-G. Hi Nitz, I have this concern too recently and spend a number of days trying to extend the validity period to like 100 years.haha. However actually i think it is not necessary.

Generating Key Pairs and Importing Public Key Certificates to a Trusted Keystore. Now any signature generated using the private key of keystore1 aliased key pair, can be properly validated. May 10, 2003 -To set up a digital certificate, Generate a key pair. The keytool utility enables you to generate the key pair. The keytool utility that ships with the J2SE SDK programmatically adds a Java Cryptographic Extension provider that has implementations of RSA algorithms.

Description¶
Generates a unique asymmetric data key pair. The GenerateDataKeyPairWithoutPlaintext operation returns a plaintext public key and a copy of the private key that is encrypted under the symmetric CMK you specify. Unlike GenerateDataKeyPair , this operation does not return a plaintext private key.
To generate a data key pair, you must specify a symmetric customer master key (CMK) to encrypt the private key in the data key pair. You cannot use an asymmetric CMK. To get the type of your CMK, use the KeySpec field in the DescribeKey response.

You can use the public key that GenerateDataKeyPairWithoutPlaintext returns to encrypt data or verify a signature outside of AWS KMS. Then, store the encrypted private key with the data. When you are ready to decrypt data or sign a message, you can use the Decrypt operation to decrypt the encrypted private key.
GenerateDataKeyPairWithoutPlaintext returns a unique data key pair for each request. The bytes in the key are not related to the caller or CMK that is used to encrypt the private key.
You can use the optional encryption context to add additional security to the encryption operation. If you specify an EncryptionContext , you must specify the same encryption context (a case-sensitive exact match) when decrypting the encrypted data key. Otherwise, the request to decrypt fails with an InvalidCiphertextException. For more information, see Encryption Context in the AWS Key Management Service Developer Guide .
The CMK that you use for this operation must be in a compatible key state. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide .

Synopsis¶
Options¶
--encryption-context (map)
Specifies the encryption context that will be used when encrypting the private key in the data key pair.
An encryption context is a collection of non-secret key-value pairs that represents additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is optional when encrypting with a symmetric CMK, but it is highly recommended.
For more information, see Encryption Context in the AWS Key Management Service Developer Guide .
Shorthand Syntax:
JSON Syntax:
--key-id (string)
Specifies the CMK that encrypts the private key in the data key pair. You must specify a symmetric CMK. You cannot use an asymmetric CMK. To get the type of your CMK, use the DescribeKey operation.
To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with 'alias/' .
For example:
- Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
- Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
- Alias name: alias/ExampleAlias
- Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias
To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey . To get the alias name and alias ARN, use ListAliases .
--key-pair-spec (string)
Determines the type of data key pair that is generated.
The AWS KMS rule that restricts the use of asymmetric RSA CMKs to encrypt and decrypt or to sign and verify (but not both), and the rule that permits you to use ECC CMKs only to sign and verify, are not effective outside of AWS KMS.
Possible values:
- RSA_2048
- RSA_3072
- RSA_4096
- ECC_NIST_P256
- ECC_NIST_P384
- ECC_NIST_P521
- ECC_SECG_P256K1
--grant-tokens (list)
A list of grant tokens.
For more information, see Grant Tokens in the AWS Key Management Service Developer Guide .
Syntax:
--cli-input-json (string)Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
See 'aws help' for descriptions of global parameters.
Output¶
PrivateKeyCiphertextBlob -> (blob)
The encrypted copy of the private key. When you use the HTTP API or the AWS CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.
PublicKey -> (blob)
The input plain text will be divided into blocks and each block will beencrypted with the key provided and hence identical plain text blocks are encrypted intoidentical cipher text blocks. CBC mode ishighly recommended and it requires IV to make each message unique. Hence, you must always use an IV of 128 bits (16bytes) with AES.AES provides 128 bit, 192 bit and 256 bit of secret key size forencryption. Aes encryption key generator java download. When a symmetric cipher mode requires an IV, the length of the IV mustbe equal to the block size of the cipher. If no IV is enteredthen default will be used here for CBC mode and that defaults to a zero basedbyte16.The AES algorithm has a 128-bit block size, regardless of whether you key length is256, 192 or 128 bits.
KeyId -> (string)
Specifies the CMK that encrypted the private key in the data key pair. You must specify a symmetric CMK. You cannot use an asymmetric CMK. To get the type of your CMK, use the DescribeKey operation.
