tlslite.utils.pem module

tlslite.utils.pem.dePem(s, name)

Decode a PEM string into a bytearray of its payload.

The input must contain an appropriate PEM prefix and postfix based on the input name string, e.g. for name=”CERTIFICATE”:

-----BEGIN CERTIFICATE-----
MIIBXDCCAUSgAwIBAgIBADANBgkqhkiG9w0BAQUFADAPMQ0wCwYDVQQDEwRUQUNL
...
KoZIhvcNAQEFBQADAwA5kw==
-----END CERTIFICATE-----

The first such PEM block in the input will be found, and its payload will be base64 decoded and returned.

tlslite.utils.pem.dePemList(s, name)

Decode a sequence of PEM blocks into a list of bytearrays.

The input must contain any number of PEM blocks, each with the appropriate PEM prefix and postfix based on the input name string, e.g. for name=”TACK BREAK SIG”. Arbitrary text can appear between and before and after the PEM blocks. For example:

-----END TACK BREAK SIG-----

All such PEM blocks will be found, decoded, and return in an ordered list of bytearrays, which may have zero elements if not PEM blocks are found.

tlslite.utils.pem.pem(b, name)

Encode a payload bytearray into a PEM string.

The input will be base64 encoded, then wrapped in a PEM prefix/postfix based on the name string, e.g. for name=”CERTIFICATE”:
