SYNOPSIS
pkcs1-conv [{--private-rsa-key|--public-rsa-key|--public-key-info} [--base-64]] < FILEDESCRIPTION
This manual page documents briefly the pkcs1-conv command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.pkcs1-conv converts private and public RSA keys from PKCS #1 format to sexp format.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').By default pkcs1-conv expects a PEM-encapsulated RSA key on standard input, and will determine its type from the Pre-Encapsulation Boundary. To convert a DER-encoded (non PEM-encoded) key, one of the first three options below must be used:
- --private-rsa-key
- Specify that a DER-encoded RSAPrivateKey, as defined by PKCS #1 (RFC 3447), and described in section A.1.2 of its appendix A, is to be expected as input.
- --public-rsa-key
- Specify that a DER-encoded RSAPublicKey, as defined by PKCS #1 (RFC 3447), and described in section A.1.1 of its appendix A, is to be expected as input.
- --public-key-info
- Specify that a DER-encoded SubjectPublicKeyInfo, as defined by PKCS #6, and described in section A.1 of its appendix A, encapsulating an RSAPublicKey, is to be expected as input.
- --base-64
- Together with --private-rsa-key, --public-rsa-key, or --public-key-info, specify that base64 encoding is applied on top of the DER encoding.
- -?, --help
- Show summary of options (not implemented).
- -V, --version
- Show version of program.
DIAGNOSTICS
pkcs1-conv will complain and exit with a status of 1 if the input doesn't match expectations. In PEM mode (when no option is used), if no PEM block is found, pkcs1-conv will output nothing but exit with a zero status.EXAMPLES
$ openssl genrsa -out privkey.pem $ pkcs1-conv < privkey.pem > privkey.sexp $ openssl rsa -in privkey.pem -outform DER -out privkey.der $ openssl rsa -in privkey.pem -outform DER -pubout -out pubkey.der $ pkcs1-conv --rsa-private-key < privkey.der > privkey.sexp $ pkcs1-conv --public-key-info < pubkey.der > pubkey.sexp
