| 2 | ================================================== |

| 4 | Python-RSA implements encryption and signatures according to PKCS#1 |
| 5 | version 1.5. This makes it compatible with the OpenSSL RSA module. |
| 6 | |
| 7 | Keys are stored in PEM or DER format according to PKCS#1 v1.5. Private |
| 8 | keys are compatible with OpenSSL. However, OpenSSL uses X.509 for its |
| 9 | public keys, which are not supported. |
| 10 | |
| 11 | :Encryption: |
| 12 | PKCS#1 v1.5 with at least 8 bytes of random padding |
| 13 | |
| 14 | :Signatures: |
| 15 | PKCS#1 v1.5 using the following hash methods: |
| 16 | MD5, SHA-1, SHA-256, SHA-384, SHA-512 |
| 17 | |
| 18 | :Private keys: |
| 19 | PKCS#1 v1.5 in PEM and DER format, ASN.1 type RSAPrivateKey |
| 20 | |
| 21 | :Public keys: |
| 22 | PKCS#1 v1.5 in PEM and DER format, ASN.1 type RSAPublicKey |
| 23 | |

| 26 | Public keys from OpenSSL |
| 27 | -------------------------------------------------- |
| 28 | |
| 29 | To get a Python-RSA-compatible public key from OpenSSL, you need the |
| 30 | private key. Get the private key in PEM or DER format and run it |
| 31 | through the ``pyrsa-priv2pub`` command:: |
| 32 | |
| 33 | |
| 34 | Usage: pyrsa-priv2pub [options] |
| 35 | |
| 36 | Reads a private key and outputs the corresponding public key. Both |
| 37 | private and public keys use the format described in PKCS#1 v1.5 |
| 38 | |
| 39 | Options: |
| 40 | -h, --help show this help message and exit |
| 41 | --in=INFILENAME Input filename. Reads from stdin if not specified |
| 42 | --out=OUTFILENAME Output filename. Writes to stdout of not specified |
| 43 | --inform=INFORM key format of input - default PEM |
| 44 | --outform=OUTFORM key format of output - default PEM |
