Abstract

A communications platform may provide asymmetric cryptography using RSA and/or DSA algorithms using a public and private key pair. The communications platform and corresponding cryptographic function library may be modified to add compatibility with multiple public-key cryptography standards (PKCS). Compatibility with PKCS #8 format may enable the communications platform to receive and decrypt encrypted private key files from another communications platform.

Claims (58)

1 . A method of transferring private key files between two or more communications platforms, the method comprising:

receiving, by a server comprising at least one processor, a private key file;

determining that a header type of the private key file is in a first type of private key file format;

determining that the server has compatibility with the first type of private key file format;

determining that the private key file is encrypted;

calling one or more first cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the first type of private key file format; and

executing the one or more cryptographic functions.

2 . The method of claim 1 , further comprising:

determining that a header type of the private key tile is in a second type of private key file format; and

calling one or more second cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the second type of private key file format.

3 . The method of claim 1 , where determining that the server has compatibility with the first type of private key file format is performed upon initialization of the server.

4 . The method of claim 1 , further comprising:

determining that the server does not have compatibility with the first type of private key file format; and

sending at least one error message.

5 . The method of claim 1 , where the one or more first cryptographic functions comprise a password for decrypting the private key file.

6 . The method of claim 1 , further comprising:

receiving an incorrect password for the private key file; and

sending at least one error message.

7 . A computer program product, comprising:

a non-transitory computer readable medium comprising:

code to receive a command from an operator;

code to receive, by a server comprising at least one processor, a private key file;

code to determine that a header type of the private key file is in a first type of private key file format;

code to determine that the server has compatibility with the first type of private key file format;

code to determine that the private key file is encrypted;

code to call one or more first cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the first type of private key file format; and

code to execute the one or more cryptographic functions.

8 . The computer program product of claim 7 , further comprising:

code to determine that a header type of the private key file is in a second type of private key file format; and

code to call one or more second cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the second type of private key tile format.

9 . The computer program product of claim 7 , where determining that the server has compatibility with the first type of private key file format is performed upon initialization of the server.

10 . The computer program product of claim 7 , further comprising:

code to determine that the server does not have compatibility with the first type of private key file format; and

code to send at least one error message.

11 . The computer program product of claim 7 , where the one or more first cryptographic functions comprise a password for decrypting the private key file.

12 . The computer program product of claim 7 , further comprising:

code to receive an incorrect password for the private key file; and

code to send at least one error message.

13 . An apparatus, comprising:

a memory for storing a database; and

a processor coupled to the memory, in which the processor is configured:

to receive, by a server comprising at least one processor, a private key file;

to determine that a header type of the private key file is in a first type of private key file format;

to determine that the server has compatibility with the first type of private key file format;

to determine that the private key file is encrypted;

to call one or more first cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the first type of private key file format; and

to execute the one or more cryptographic functions.

14 . The apparatus of claim 13 , where the processor is further configured:

to determine that a header type of the private key file is in a second type of private key file format; and

to call one or more second cryptographic functions from a cryptographic function library, the one or more cryptographic functions being compatible with the second type of private key file format.

15 . The apparatus of claim 13 , where the processor determines that the server has compatibility with the first type of private key file format upon initialization of the server.

16 . The apparatus of claim 13 , where the processor is further configured:

to determine that the server does not have compatibility with the first type of private key file format; and

to send at least one error message.

17 . The apparatus of claim 13 , where the one or more first cryptographic functions comprise a password for decrypting the private key file.

18 . The apparatus of claim 13 , where the processor is further configured:

to receive an incorrect password for the private key file; and

to send at least one error message.
