i found this :
for example the real 3.60 keys are:
[appldr]
type=SELF
revision=0010
version=0003006000000000
self_type=APP
erk=A5E51AD8F32FFBDE808972ACEE46397F2D3FE6BC823C8218EF875EE3A9B0584F
riv=7A203D5112F799979DF0E1B8B5B52AA4
pub=50597B7F680DD89F6594D9BDC0CBEE03666AB53647D0487F7F452FE2DD02694631EA755548C9E934
priv=
ctype=25
but these keys are diffirent in 4.25 Appldr
here :
[appldr]
type=SELF
revision=0010
version=0003006000000000
self_type=APP
erk=F239349F6472817C6251713DFA2F6A05164B7B37514C660ECDB83B96E6CF2991
riv=29E4B2179AC9DD72A66A1886205751F9

priv=
ctype=25
the first keys can decrypt 3.60 eboots but the 2nd cant
