  script_tag(name:"insight", value:"This update for python-PyJWT fixes the following issues:

python-JWT was updated to 1.5.3. (bsc#1186173)

update to version 1.5.3:

 * Changed

 + Increase required version of the cryptography package to >=1.4.0.

 * Fixed

 + Remove uses of deprecated functions from the cryptography package.
 + Warn about missing algorithms param to decode() only when verify
 param is True #281


update to version 1.5.2:

Ensure correct arguments order in decode super call [7c1e61d][7c1e61d]

Change optparse for argparse. [#238][238]

Guard against PKCS1 PEM encododed public keys [#277][277]

Add deprecation warning when decoding without specifying `algorithms`
 [#277][277]

Improve deprecation messages [#270][270]

PyJWT.decode: move verify param into options [#271][271]

Support for Python 3.6 [#262][262]

Expose jwt.InvalidAlgorithmError [#264][264]

Add support for ECDSA public keys in RFC 4253 (OpenSSH) format
 [#244][244]

Renamed commandline script `jwt` to `jwt-cli` to avoid issues with the
 script clobbering the `jwt` module in some circumstances. [#187][187]

Better error messages when using an algorithm that requires the
 cryptography package, but it isn't available [#230][230]

Tokens with future 'iat' values are no longer rejected [#190][190]

Non-numeric 'iat' values now raise InvalidIssuedAtError instead of
 DecodeError

Remove rejection of future 'iat' claims [#252][252]

Add back 'ES512' for backward compatibility (for now) [#225][225]

Fix incorrectly named ECDSA algorithm [#219][219]

Fix rpm build [#196][196]

Add JWK support for HMAC and RSA keys [#202][202]");
