check this option checks the consistency of an RSA private key. modulus this option prints out the value of the modulus of the key. noout this option prevents output of the encoded version of the key. text prints out the various public or private key components in plain text in addition to the encoded version. These options can only be used with PEM format output files.
Utility to read in an encrypted key with no encryption option can be used to remove the pass phrase from a key, or by setting the encryption options it can be If none of these options is specified the key is written in plain text. des|-des3|-idea These options encrypt the private key with the DES, triple DES, or the IDEA ciphers respectively before sgckey use the modified NET algorithm used with some versions of Microsoft IIS and SGC keys. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in passout password the output file password source. The output filename should not be the same as the input filename. If any encryption options are set then a pass out filename This specifies the output filename to write a key to or standard output if this option is not specified. passin arg the input file password source. If the key is encrypted a pass phrase will be in filename This specifies the input filename to read a key from or standard input if this option is not specified. outform DER|NET|PEM This specifies the output format, the options have the same meaning as the -inform option.
On input PKCS#8 format private keys are also accepted. The PEM form is the default format: it consists of the DER format base64 encoded The DER option uses an ASN1 DER encoded form compatible with the PKCS#1 RSAPrivateKey inform DER|NET|PEM This specifies the input format. Note thisĬommand uses the traditional SSLeay compatible format for private key encryption: newer applications should use the more secure PKCS#8 format using the
They can be converted between various forms and their components printed out.
